I was developing web apps when suddenly dolphin, yakuake and konsole started crashing upon opening.
After a couple of reboots I noticed some errors in journalctl
dic 20 17:19:04 raul-claro kwin_x11[6485]: qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 37779, resource id: 44040904, major code: 18 (ChangeProperty), minor code: 0

dic 20 17:19:05 raul-claro systemd-coredump[7733]: Process 7152 (konsole) of user 1000 dumped core.
But also some video drivers errors (i guess)
dic 20 16:50:56 raul-claro kernel: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 10ac08 [ IBUS ]
dic 20 16:51:20 raul-claro kernel: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 6013d4 [ IBUS ]
I can open firefox and visual studio code for example, but dolphin/konsole/drkonqui fails to start.
The system is updated, and there were no updates today
Any help?
