Question / Help Crash streaming or not.

Check your Intel GPU drivers. You're using the quicksync encoder, and there are some versions of Intel drivers that cause this encoder to crash.



Not sure at this point whether this is fixed in a new driver, or if rolling back is still required.

Thanks, it appears that my drivers were out of date. I'll let you know if it works. It is strange though that such a bug would cause problems when not streaming or recording.

I think it happens when OBS is setting up the encoder settings-- the file indicates QSV is your chosen encoder, and the crash log mentions the QSV thread:
