Frequent freezes and crashes in Ubuntu 20.04



I have very frequent crashes (rendering pycharm unusable) with a new machine that runs on ubuntu 20.04. I'm on kernel 5.4.0-29-generic

This is the log:

# A fatal error has been detected by the Java Runtime Environment:

I'm with the same issue on Ubuntu 22.04 with Intellij Community Edition.
