The computer crashes and logs out within 5-10 minutes after screen sharing in Zoom and Chromium (zoom web client).
During the crash, I get logged out, and I have to login again (all running applications get killed). The error keeps happening again and again, in almost every Zoom meeting.
I am using Kubuntu 22.04 (same issue also present in Kubuntu 23.04, Xubuntu 22.04 and Mint 21. Perhaps 22.04 and all later versions are affected).
I have 12 GB of RAM. I kept checking system monitor, and found that memory usage remained under 4 GB. So, the computer did not run out of memory.
Here is the stack trace, which repeatedly says
warning: Can't open file anon_inode:i915.gem which was expanded to anon_inode:i915.gem during file-backed mapping note processing
Here is a log file from the KDE crash handler.

I got zoom[2316]: segfault at 8 ip 00007f29403b6cd0 sp 00007ffdf0113438 error 4 in libQt5Gui.so.5[7f2940200000+714000] in dmesg of Xubuntu 22.04.
Does anyone know any workaround?
This issue is absent in Kubuntu 18.04, Kubuntu 20.04 and Mint 20.3 (based on Ubuntu 20.04).
My laptop model number is HP 250 G5. It has an Intel i3-6006U CPU with Intel® HD Graphics 520 (no dedicated graphics).
My other computer running Kubuntu 22.04 is unaffected, but the HP 250 G5 laptop experiences the same sort of crash in multiple distros based on Ubuntu 22.04 and later.
