I have a logitech webcam (C615), which I think is where the lvcod64.dll comes from.
For the last couple of Beta builds I've been getting this warning on startup:
A low-level exception occurred in: lvcod64.dll (GetAVICodecs)
It doesn't seem to be having any adverse effects, but can't be sure, I do most of my work in Production Premiere and only use Beta for the text editing feature occasionally.
It used to cause some havoc in the past: https://community.adobe.com/t5/premiere-pro-discussions/a-low-level-exception-occurred-in-lvcod64-dl...
