'kill <PID>' does kill it, but how do I run it again

out? Simply running plasmashell from the command line does put up the
widget panel but it's still frozen, and the command never returns.
You can (re)launch 'plasmashell' via krunner (ALT-F2)
That said, may be worth trying to get a backtrace out of the deadlocked
plasmashell process, if you have terminal access, run:
gdb -p <PID>
and issue command:
thread apply all bt
Getting a worthwhile backtrace may require installing -debuginfo packages,
via something like:
dnf debuginfo-install plasma-workspace
(warning, it's a lot, but will give much better results)
