Thanks, though I didn’t notice I had the issue you pointed. Until I checked thoroughly and came across a forum post from archlinux (that I can’t link). It was specifically the
kwidgetaddons
for me, for some reason it was installed from AUR
sudo pacman -Syu kwidgetaddons
saved it just as you also suggested.
“Foreign” packages can be listed with
pacman -Qm
You probably didn’t properly uninstall it. You’ll have to manually remove the leftovers. 
sudo rm -rf /usr/lib/modules/6.7.12-1-MANJARO
I had the same problem, but only 2 packages. Your info helped. Thank you.
Good update! Finally fixed plasma 6 desktop icons from disappearing (until re-logging, and even then their position was reset.) after editing them 
“non-issue”-issue… it works, but, kernel 6.10.0 still lacks lz4 compression for zswap:
[K aug 7 09:59:29 2024] zswap: compressor lz4 not available, using default zstd
[K aug 7 09:59:29 2024] zswap: loaded using pool zstd/z3fold
