Latest qemu won’t start with an error:
ERROR! QEMU 6.0.0 or newer is required, detected 10.0.0.
I don’t think this requires much of an explanation. You can just look at it and tell exactly what the bug is.
Anyway, there has already been two bug reports made.

The solution is to either install the git version, or rollback and lock.
