Thank you for taking your time to help me.
At this state, the crash already happen and i was just trying to revive the system with free memory hotkey. But with no success.
You can see the difference, when you look at my first crash journal from today (i posted 2 today).
Yeah exactly, but after the newest Flatpak driver, the last error changed a little (maybe because it freezed my system while i was ingame? 
)
I think so because, i saw this error since february around 7 month ago…
where i have reported this:
But since my system was still fine… on the otherside, i may could remove this grub command in Grub nvidia_drm.modeset=1 and hopefully something changed after that.
Since im not in need for Firefox H/W Acceleration anyways.
I will report back if removing the Grub command works.
