Me Too same problem on 4 different computersOBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored.

Problem found for me .. the Hardware Acceleration for Browser was enable ... put-it to disable it's fixing my issue.That is a completely different issue, and refers to the old problem of not being able to capture hardware accelerated windows using window capture. The browser hardware acceleration line there refers to the usage of hardware acceleration within OBS for page rendering.
That said, what is actually broken? What are you trying to do, and what is happening that is not expected? Screenshots would definitely help here.
