Expected Behavior

When I try to open OBS, it should open, not crash.

Current Behavior

When I go to open OBS, it crashes before the program appears on the screen. I get a crash report, and an option to try to reopen. I'm given the option to open normally or in safe mode – both result in seemingly the same crash. I do not have any plugins or unusual aspects of my setup that I'm aware of.

Steps to Reproduce

1. Press cmd+space, type obs, click enter
2. I get small window saying "OBS did not shut down properly during your last session. Would you like to start in Safe Mode(...)? Options are "Run in Safe Mode" and "Run Normally."
3. Clicking either results in a crash 1-2 seconds later, without any sign of OBS loading.

Note: I haven't yet restarted the computer; I decided to report this bug first in case I cannot reproduce it.

Anything else we should know?

The crash report was too long for this field, so I saved it as a plain text file.

This is a known issue, and a fix is being worked on. It has to do with the scene collection ending up in a "corrupt" state if you have an unclean shutdown after removing a Video Capture Device source.

You should be able to resolve this in the meantime by loading the backup scene collection. You can do this by going into the ~/Library/Application Support/obs-studio/basic/scenes folder, removing the .json file for your scene collection, and then renaming the .bak file for the scene collection to just <your scene collection>.json.

If that does not resolve the issue, you should also be able to temporarily revoke the Camera permission from OBS, which will prevent the race condition from occurring on startup.
