I noticed Alexandre's build on fedora36-ty-3 was hanging in oe-selftest:

https://autobuilder.yoctoproject.org/typhoon/#/builders/86/builds/4815

Looking at the bitbake-cookerdaemon.log, we see:

to-worker/oe-selftest-fedora/build/build-st-1756321', 'OLDPWD': '/home/pokybuild/yocto-worker/oe-selftest-fedora/build'}, ['/home/pokybuild/yocto-worker/oe-selfte
st-fedora/build/bitbake/bin/bitbake', '-e']]

and then pings are keeping things alive but it looks like the idle thread has crashed. I saved the log into ~/saved.

(gdb) py-bt

which shows the idle thread is missing due to the exception. I'll kill
the remaining process since it will never get anywhere.

Cheers,
