OBS Audio Sync Issue with Web Presenter

Hello,

I've had an issue on multiple livestreams where the audio and video go out of sync. The sync is checked and fine for a while (30-60mins) and then jumps out by about 1 second randomly during the stream. It then stays out of sync by about a second (doesn't drift further). If I quit and re-open OBS the audio and video are back in sync for a period of time, and then go out of sync again.

I've attached the specs of the encoder PC I'm using, and we are on OBS 32.0.4. Log files are attached as well. We are using a Blackmagic Web Presenter as a capture card.

Thank you!
