nxdumptool-rewrite - System crashes if Joy-con is disconnected during dumping while on airplane mode about nxdumptool HOT 5 OPEN

I know this is a very oddly-specific (and unlikely) circumstance (and also beta builds tend to be buggy in general), but I'm submitting this report in case this is indicative of a much larger issue, and also to prevent this from possibly happening to anyone else

Hi there. I've been trying to reproduce the issue on my own using my Erista unit (sysMMC, Atmosphère 1.6.2, flight mode enabled, latest rewrite build) and I can't get it to crash. I even reconnected both Joy-Cons to the console and took them out -- the process still continues just fine.

Since this appears to be a system-wide crash and no meaningful error information is part of your logfile, please take a look at the /atmosphere/fatal_errors/ directory in your SD card.

If there are too many files in there, just delete all of them (preferably using Hekate UMS) and reproduce the crash once more, then share the generated file(s) here.

Unable to reproduce here either.

I've looked at the "fatal_errors" folder, but it appears to be empty. I don't homebrew the Switch often due to fear of bans, so I'm not sure if the logging is something that needs to be enabled or such (I don't mess with the defaults). It's possible it might have something to do with me using emuMMC and you using sysMMC (I'm too chicken to use CFW on sysMMC haha), but I'm not sure. If it's also worth nothing, my emuMMC was a "SD File" and not an "SD Partition".

Update: I've enabled debugmode_user in exosphere.ini, and I will try this glitch again. debugmode already appears to be enabled.

Update: So I figured out that while dumping the game, NXDumpTool disables the recognition of most inputs (including the disconnection of the joy-cons). The homebrew program only seems to recognize the joy-cons were disconnected once the program is either done dumping the ROM, or encounters an error when reading the game card. If the program encounters an error when it is reading a game card (i.e. dirty contacts or outside interference) and prompts the "You must have Joy-Cons connected on flight mode" message, the progam hangs (along with all inputs) upon closing the OS pop-up, but I figured out that if you remove the game card, the program unhangs itself, since removing the game card forcefully cancels the dumping operation (holding down B doesn't seem to work). This was done for game card dumping though, but I'm not sure about digital title dumping.

Because the system never truly froze (NXDumpTool just disables virtually all buttons and inputs, mimicking a hard crash), there were no error logs to generate.
It may be worth adding "removing the game card" as a possible "bug fix" if this issue becomes prevalent.
