Noel,
I have tried to open sessions and templates with 2020.11 and 2020.11 update 1 and they both crashed. Here is the minidump file for 2020.11. I'm not able to send the second dumpfile because of the upload size limitation. Is there another way I can send the file to you?
File: Untitled_11242020_160934.dmp is with out the latest update.
