Hello,
Ever since switching from 5.17.8 to 5.18, I have been seeing a very intermittent bug that causes multiple programs to freeze.
[29979.091868] BUG: kernel NULL pointer dereference, address: 00000000000000d6

Appears to be the culprit; however it happens very intermittently (as seen here, took more than 8 hours), so I have not been able to dissect which update broke it.

I have tried multiple UEFI versions including the latest available, and have not found anyone with a similar problem.
I have also removed all third-party kernel modules just in case.
Thank you in advance for a clue as to what's causing it/where I can get help.
Your hardware is relatively new and kernel 5.18 has produced lots of bad reports so far. You may find it better to downgrade to 5.17 until things stabilise.
