Adding Video Capture Device or viewing its properties causes OBS to hang

[Bassquake]

As soon as I add a Video Capture Device the popup comes up blank (see image below), OBS hangs and have to force quit. When I reopen OBS, the Video Capture Device is listed in Sources but if I click the properties of it, it'll show empty popup and hang.

Logs show no errors: https://obsproject.com/logs/d0F62OBsLGuOcqL1

Here's the crash report: https://obsproject.com/logs/WXbZ6iIZBuZQmCr5

Running Windows 22H2, have tried the following:

• Updated Nvidia 1060 drivers (using Studio drivers)
• Reinstalled OBS 29.0.2
• Uninstalled all 3rd party plugins
• Disabled hardware-accelerated GPU scheduling in Windows settings
• Xbox Game mode is on
• Checked with Nirsoft InstalledCodec to check no codec errors

Appreciate help.

Can't seem to edit my original post. I noticed the crash report is a very old one but it was the only file in the crash folder. Deleted it but no new ones get added after a crash occurs.

Edit: Adding what Windows reports:

The program obs64.exe version 29.0.2.0 stopped interacting with Windows and was closed. To see if more information about the problem is available, check the problem history in the Security and Maintenance control panel.

This is caused by outdated VTuber software. Update/remove it or try the 29.1 beta which blocks it from loading.

Don't seem to have VTuber installed but uninstalled OBS then installed the 29.1 beta4 and it doesn't crash now. Thanks.

It might have been Flipside Studio virtual camera because that no longer shows in OBS anymore. I did uninstall it before but OBS still crashed so assumed it wasn't that. Reinstalled it but it doesn't show in Video Capture Device. Will contact the Flipside makers for an update.

That certainly looks like it could be based on the same buggy code as the VTuber programs that freeze, we added a generic DLL block for programs that use the default unity capture filename (we don't target Flipside Studio specifically) and it looks like that's kicking in when you run the beta. If you look at the end of a log file after exiting OBS it will confirm.

If you're in contact with them, they will need to implement this patch to their capture DLL: https://github.com/schellingb/UnityCapture/commit/2eabf0f and release it under a new DLL name.

Many thanks, have submitted bug report to them. Hopefully gets sorted soon!
