I can confirm that I also run into this on my machine.
Didn't investigate until one time it froze the entire screen completely and I had to reboot by holding down the power button.
I don't think I was using krunner at the time, just tabbing between windows.
Reading journalctl -r after the fact logged these messages many times a second. I also had these ones about key repeat discard, unsure if related or just caused by the slowness.

(lol hi sam)
Same issue here! It causes huge system-level stutters for me (audio, mouse moves slowly, plasma frame drops).

The problems seems to have disappeared in a recent version of either linux-asahi, mesa-asahi, or KDE:
These versions aren't in nixos-apple-silicon yet. Could someone else confirm if the problem is fixed?
I believe Lina fixed this
Overview
I do not know how to reproduce the problem reliably at this point, but this is the pattern:
asahi_sched
kworker pins a cpu to 100%I reckon it happens maybe 10% of the times I open krunner, but I can't get it to happen by killing and relaunching it many times in a row.
Perf
Here's what I got from perf when it was happening one time:
