It's my understanding that Rosetta allows apps designed for Intel-based Macs to run on Silicon Macs. If this version of MC is built to run on Apple Silicon then it's a non-issue. I appreciate your trying to help. Are any other users having similar problems? What are my next steps to troubleshoot this?
MediaCenter28 is a universal app, it contains a full silicon build and a full intel build in a universal or "fat" binary.
It runs under silicon natively unless you open it's info in the finder and check the option to run under rosetta.
Anyway, I just tested that on my M1 and it works fine both ways.
I want to confirm with you that you re-downloaded the current build, 28.0.105 and reinstalled it by mounting the .dmg and dragging the Media center 28 app in that disk image window to your applications folder link in that window?

the Apple crash dump info (you can copy and paste it from the report that would be "sent to apple" into a message).
You could also take a short video of trying to run it up until the point it crashes and send that as well.
