I have updated the plasma to the latest release (6.6.0) and now I am getting whole system freezes when I am using intellij idea at the random time. I am not a pro user, so I wanted to ask for help to identify or solve the problem.
The system got stuck fully: no mouse movement, no keyboard answers, no display changes no ssh connection available. It like gets frozen: the audio disappears (just stops, not loops over) and the display picture just freezes (no black screen, nothing. Just freezes in one state)
It does happen only when I run intellij idea. Below will be the trimmed stack trace of the error the kde has popped out couple of times (maybe it helps)
Another thing: On my other PC (manjaro laptop) I have also updated to the latest, but there is everything ok. Maybe because it is using custom manjaro kernel there?
What I have tried to do:
- Update bios to the latest version (no change)
- Open the KSystemLog on the second monitor and wait for the freeze (have noticed no fatal error or something when the system freezes)
- lts kernel (6.12.74-1-lts (64-bit)) - nothing has changed. Same freeze

Maybe there is a different way to get the logs to find out, why the system freezes?
Have also made a bug report if needed https://bugs.kde.org/show_bug.cgi?id=516448
