I’ve been having a problem with updating to kernel 6.1.x. As the title says, plasmashell dumps core the moment my WiFi NIC connects. The machine hard locks and I need to physically turn it off and back on (no, I can’t even ssh in). Booting back to kernel 6.0.x is totally fine. Here is the pastebin of the relevant portion of my system logs.
It’s pretty cut and dried. The moment it authenticates, plasmashell dumps.

This is ONLY with Kernel 6.1. Kernel 6.0 is happy.
Should you land here from Google, I believe what the problem was, although I hadn’t found any log to prove it, is that I had AUR versions of the VirtualBox kernel modules installed. I’ll be honest and I don’t remember WHY I installed the AUR ones when there are blessed ones. I removed the AUR package and let pacman install the the blessed one and everything seems fine.
The takeaway is that if you are installing non-tested kernel modules, YMMV…
