Unity complains about handles from previously crashed unity

[twobob]

Unity 2021.2, crashes.

Try to open again. Handle warning. Digging finds the handles are grabbed by unity shader compilers and unity instances.

EDIT: Killing everything - one by one hours later… So it was in fact one of the batch unitys that was not dying?
