Laptop Froze during zoom call

Hello everyone.

I was just recording a zoom call and my laptop froze 40 minutes in. I have a feeling it was a hardware issue on my end but I wanted to ask if anyone had their computer  freeze on them mid-call? 

I have a 13th Gen Intel(R) Core(TM) 19-13900H (20 CPUs) `2.6GHZ, 16384MB RAM

I was running Audacity to record my audio locally (better quality) and OBS to record guest audio externally for safety. I've recorded about six calls on this laptop so far and this was the first incident.
