After OBS updates my webcam stops working. 31.0.4

[Bilboster]

This happens with every update. To fix the problem, you have to roll back to version 30.1.1 or even earlier.

Webcam - Logitech C922
Works in all other applications without complaints. In parallel with the launch of the OBS, there are no other applications that could conflict.

It was not possible to find solutions on the Internet. Everywhere they write about the USB connector, updating / reinstalling drivers and privacy policy - this does not help. The only option is to roll back to an older version.

try uninstalling Kaspersky, removing the source in OBS, restarting your computer, and then adding the source again.

And if I can’t remove Kaspersky, is there no other option?

And why should I delete something to make something that WORKED before WORK?

You could work with Kaspersky support to see if they can assist in troubleshooting, or finding the right combination of settings to not interfere? ... see below

And why should I delete something to make something that WORKED before WORK?

Presumably your Operating System and Kaspersky have been automatically updating, and security software, working at kernel level, can do all sorts of things (for good and sometimes not). So, that 'it worked before' can be misleading, as your system changes (typically) monthly... and Microsoft QA leaves a LOT to be desired of late
So uninstalling potentially problematic software is a good test/troubleshooting step. I'm not saying leave Kaspersky uninstalled, just uninstall to test. If all works with Kaspersky uninstalled, and issue re-appears when you re-install it, then it might be one of the User (and/or corporate applied) settings, or could be an interplay between Kaspersky and the Operating System. Either way, Kaspersky support is who you'd work with to address such (or your company IT/security team, if Kaspersky is employer controlled security software)

Reach out to whoever is an administrator on the computer who can.

Reinstallation helped. Only I had to reinstall several times. I didn't touch Kaspersky at all.
