Continues to freeze after laptop has been updated and video bitrate has been changed

Running Tahoe 26.3 is part of this - OBS 32 hasn't been fully tested on the beta yet and there've been some stability reports. But even without that, M1 Air with 8GB + no active cooling tends to thermal throttle around the 45-50 min mark during sustained encoding. Open Activity Monitor while streaming and watch memory pressure and CPU usage - if it goes red near the freeze point, that's likely your culprit.

The CPU usage does tend to get high around that mark, and if I get a fan for the laptop should that solve the issue or just wait until there’s been more testing done
 
A cooling pad helps a little but won't fully fix it - M1 throttling happens at the chip level when it hits its power limit, not just from chassis heat. What makes a bigger difference is dropping to Apple VT H.264 encoder instead of x264, and lowering bitrate to around 3500-4000 kbps. I've done a lot of long recording sessions on Mac and software encoders like x264 just run the chip too hot after 40+ min.
