I too have had that happen with recent kernels, but have not yet put
a finger to a specific version or cause.

Just toggling the power button on the wireless mouse is enough for
it to "re-appear".

The 5.4.xx kernels never had this issue.  I went straight from those
to the 6.3.xx ones, where it does happen sometimes, both with and without
the recent "delay" fixes.
