-- Information about the crash:
I have a laptop with nvidia gpu and intel cpu. I have the up to date kde neon unstable. This issue had been happening eversince installing it the first time more than a month ago. I turn my laptop on, the os boots normaly, and after logging into my account, one of the monitors begins heavily flickering, like a lot. Sometimes its the monitor connected via usb-c (dp alt) that flickers, sometimes it's the one connected via HDMI. For this crash, it was the one connected via HDMI. After unplugging the monitor, watiting a few seconds, and replugging, the issue is fixed but i see that a crash had occured.

The crash can be reproduced every time.
