Cannot get render to work

Hello;

I read the 'before you post' and will email support files shortly.

I have not used this product on any other machine (yet).

It runs well and everything looks and sounds great, but I cannot get a render to work yet.

Brand new Dell / Alien Aurora R13

i9-12900KF

32GB Ram

64bit windows 11 pro

GeForce RTX 3080Ti 12 GB

I have tried multiple things. Using default AVPro give message of 'AVP Video Render Format Unsupported' after doing the audio. It redoes the audio every time which makes debugging/testing this a time consuming process.

Tried multiple quality, resolution etc.

When I switch to 'basic rendering'

then if I try that it shows the below screen then crashes:

Thank you in advance;

Joe Ruder
