OBS keeps crashing - Fresh install on iMac newly upgraded to BigSur

Hello,

I've been having issues with OBS crashing on my Imac. I had been using the Apple Hardware Encoder in OBS for some time, but that caused some other issues that I was unaware of. After reading a number of articles, I switched to x264, but now OBS keeps crashing. The stream quality is far better than the Hardware Encoder, so trying to figure out the issue.
After the first few crashes, I finally took the step and upgraded my iMac to Big Sur hoping that might fix the issue. I then deleted OBS and the Application Support files in Library. Restarted everything, installed OBS fresh, got everything set up and it's still crashing. I have included the OBS Log from the latest crash as attached a txt of the Apple Crash Report (message was too long with the full thing. Thanks!)

Greatly appreciate anyone that can offer their input on what might be causing this and how to fix it.
Thanks!
