App aborted with error: "Error launching engine: The application “Gmail” could not be launched because a miscellaneous error occurred. The app may not have launched properly. If it did, the engine will not be properly cleaned up upon quitting." [main(665)] about epichrome HOT 10 OPEN

Does this happen consistently if you reboot with an Epichrome app open, and set to open all windows? Because of the way Epichrome hot-swaps the engine in at runtime, it does seem possible to me that apps will not reopen properly this way, but I haven't tested it myself. Thanks!

OK, thanks for the update! I'll try to reproduce this on my system and see if I can figure out what's going on. As I mentioned, I do have a suspicion that it might be that it simply can't be done, and apps will have to be launched by hand after a restart. But I'll keep you posted.

this also happens to me every time on reboot - all open Epi apps report errors on attempted restart. however, Epichrome Scan doesn't (usually) find any corruption or anything.

they report the following - a missing JSON file that cannot be moved, and then a timeout. fwiw, these are all Brave apps.

if there is a concurrency problem, maybe add some random backoff on restart, or a mutex (lockfile?) of some sort? or maybe they just need a much longer timeout on restart, since there is so much going on that things are really slow..

Yeah, it could well be a timeout problem given all the stuff going on in the system at login. I'll look into it. Thanks!

I'm having trouble reproducing this exactly, though I've experienced a different problem. In my tests, Chrome-based apps reopen just fine on reboot. Brave-based apps do not attempt to reopen at all.

Can people let me know if they're experiencing these failures with Chrome- or Brave-based apps? I'm not sure there's anything I can do about it, but I could try blindly lengthening the timeout to see if that helps.

For me, these are all Brave apps, and they all try unsuccessfully to restart after a reboot. If I remember to shut them all down first, they manually restart without issue.

It's so odd, I can't get my Brave apps to try to reopen at all. I've tried changing Brave startup settings and the "Close windows when quitting an app" setting in System Preferences->General but no dice, so I don't have a way to diagnose this myself. I'll increase the timeout for the next release and let's see if it makes a difference.

Version 2.4.5 will be up shortly, and I've added a retry to the launch code, in the hope that if it fails the first time on reboot, it will succeed on a second attempt. If you continue to get this errors on reboot after updating to 2.4.5, please let me know and I'll see if there are any other things I can try. Thanks!
