Any chance get portable version?

I was hoping not ... Apparently the new file detection system is a bit too slow. For example:
With previous versions, I entered the command for a batch of 25 ep with a total of 55gb and its corresponding HEVC, always 25 ep, (used to decrease the total size).
In 3/5 seconds came the message that the command was OK. At that point I checked and in a short time (no more than 2-3 minutes) the check finished.

Now, just to paste the command and wait for the OK from the program, it also takes 10 15 minutes.
I'm not talking about the check ... (for a batch like the one described above I left the pc all night and in the morning it was still doing the last 2 episodes).

If speed couldn't be improved, wouldn't it be possible to reintroduce the old system together with this new one? So you can choose (after all the BOM problem is mostly about files NOT already inside MKV).
I didn't write this issue right away because I wanted to understand if it was due to these 50gb batches (2 - 3gb for single file) or if it was in general. In the end it is both for the file size and in general.
Thanks in advance

As the title suggests, I went into batching to export to MKA / S.
And apparently it works. Except that it exports to .MKV (thankfully MKV toolnix sees it anyway) I know that BulkRename would be enough to change .mkv to the right one.

The system to make the batch work (which I finally understood):

C:\Users\MSI\Downloads\EXE\mkvtoolnix\mkvmerge.exe --ui-language it --output ^"G:\Backup Anime\[KonaWolf Fansub] Miru Tights - 01v2 [BD].mks^" --no-audio --no-video --sub-charset 2:UTF-8 --language 2:it --track-name 2:KonaWolf --default-track 2:yes ^"^(^" ^"C:\Users\MSI\Downloads\Telegram Desktop\[KonaWolf Fansub] Miru Tights [BD]\[KonaWolf Fansub] Miru Tights - 01v2 [BD].mkv^" ^"^)^" --title ^"^"
is the original command from MKVToolNix GUI

Just add --track-order 0:2 to the end of the command.
0:2 must be replaced with track order (in my case for MKVToolNix it is seen as 0: 2, obviously if you move the tracks, the values also change).

Problem:

Export to .mkv

Anyway thanks to this I can now batch 800 episodes to extract audio / subs only 👍😁👌😵🐱‍🏍

Jobs in this list even if they are deleted, when you start the worker they are executed.

How to reproduce error:

Add a Job,
Go to the Job list and delete it,
add another job,
start the worker...
= The job you deleted starts.

I actually encountered this problem in previous versions as well.
Thanks in advance (as you can see I've done nearly 200 jobs by now😁)

Remarks:
Eventually I did the batch individually and MkvToolNix pointed out to me that of the MKS 4 and 5 have a character set problem (it continued anyway). It could be the one that blocked the software.

I have been experiencing an anomalous problem with the program for some time now.
Sometimes, copying the command to the program returns that the command is ok but both adding to the queue (and starting it) and checking the consistency (or any other option) DO NOT give results, as if I had never pressed the key.

In this case in the command you will notice that the files are not identical to the originals, I thought the problem was in the names (and instead even renaming and changing the file structure the problem persists)

I don't understand, both V1 and V2 don't say why. Basically I have to batch a 64 episode series, I have to change the original video track with the hevc version and delay it for 1000ms. I do all the necessary things and copy the command from the shell. I paste the command and do analyze, it says OK (Structure looks OK :).

I click on process and says ok for all 64 in type 20 total seconds. No new files are created and nothing happens.

Found the problem but I don't know why it happens: C:\Users\MSI\Downloads\EXE\mkvtoolnix\mkvmerge.exe
if put as shell, when you do output command (the one to see what it would do) it doesn't put " \ " in the path (only for the path of mkvtoolnix). Fix: "" at the beginning and end. It happens with both V1 and V2.

i keep getting this error please help

MKVBatchMultiplex.log

When you do an "abort job" (also the other one, the one next to it), it aborts ... yes ... but it also causes the subsequent batches to go into abort (those you add + those already present in the list ).
Both keys cause any job to abort. You must then close and reopen the program to continue using it.

Almost 90% of the times I enter the command I get this error:

Almost everything I try to automate with this tool gives me this error.

I am also having the same issue. (Sorry for bad English)
Version 2.1

Default Location (C:/Program Files/)
So, what I did was that i wanted to cancel a job/task so to cancel it, I go the task manager and just "End Task" the task, this was the first time i did this to cancel it. After few seconds i have the Windows blue Screen and then my computer restart. After computer restart i try opening the software but shows "Failed to execute script RunApp". So, i download the lastest version with a clean install but same error. Same with portable version and older versions. Now i can't run the software no matter with version. Could solve this problem please?

How can I fix it?
I am using debian 11 . And python 3.9.2
Thanks a lot

Everything is installed. Program starts but starting workers doesn't start a process.. Readthedocs says mediainfo path has to be in path. Well they don't provide what the path variable should be though. But my mediainfo executable is in /usr/bin/mediainfo. /usr/bin is in my path obviously. Actually no version of this program works for me. The git version won't even install even with different python versions from pyenv... Installing via pip in python 3.8.1 clicking start workers doesn't even do anything.

At startup the app give this error:

It's a upgraded from 2.0.0dev.

I noticed the program removes titles even if they were properly set in mkvtoolnix.

Example:
This is the command gotten from mkvtoolnix.

"C:\Program Files\MKVBatchMultiplex_internal\embed\mkvtoolnix\mkvmerge.exe" --ui-language en --priority lower --output ^"C:\Users\PC1\Desktop\Tsuki ga Michibiku Isekai Douchuu - S2 EP11.mkv^" --attachments 2,3,4,5,6,7,8,9,10,11,12,13,14,15 --language 0:und --track-name 0: --display-dimensions 0:1920x1080 --language 1:ja --sub-charset 2:UTF-8 --language 2:en ^"^(^" ^"C:\Users\PC1\Desktop\Tsuki ga Michibiku Isekai Douchuu 2nd Season\Tsuki ga Michibiku Isekai Douchuu - S2 EP11.mkv^" ^"^)^" --title ghjjhgjh --track-order 0:0,0:1,0:2

Title was changed to "ghjjhgjh" on this particular episode, Episode 11

This is the command created for Episdoe 11. Title has been reset to the default value
