Post a recording. And use the built-in log uploader in OBS's Help menu. Paste that URL into your next post, and into the Analyzer that you can get to from my signature.
Record about 60 seconds or so, just so things have time to stabilize if they're going to, stop recording normally, wait for that to finish, and close OBS. Then reopen and upload the previous session (the one that made the recording). Give us all of that to work with: recording and logfile *from the same session*, in a format that the Analyzer can use. And of course it needs to demonstrate the problem too. :-)
