I have to be honest, I never waited more than a few tens of seconds (I'm
usually working) before killing kwin and running it again from a virtual
console.
if I run it like:
mdione@nimbus:~$ DISPLAY=:0 kwin --replace 2>&1
and using a tool to prepend output lines with a timestamp, I can see the
following lines being written around the time the freeze occurs:

Similar log lines appear once I start the new kwin instance, so I'm not sure
this really helps you tracking it down.
Also, as you can see, C-c does not kill it, and I have to use kill -9 to finish
it. Next time it happens (1-2 times a day, sometimes more like 5-10) I'll try
to attach a strace to see where it's hung.
I also see this in the logs:
2023-01-26T10:03:40.992345: kwin_xkbcommon: XKB: inet:334:58: unrecognized
keysym "XF86EmojiPicker"
Again, not sure what of all this helps you.
