--- Comment #13 from kts <jeckfer...@gmail.com> ---
It dumped core again with 5.12.12 or 5.12.13, I'm not sure as to which because
it happened after update to 5.12.13. The result is same. No crash or
interference just core dump. killall kactivitymanagered and kactivitymanagered
--start-daemon worked smoothly because the crash is intermittent and normally
it's fine only occasionally it manifests. Below is the coredumpctl backtrace:

As a mention, quite recently every fundamental component of KDE is running
flawlessly especially kwin. So far, I only have core dump of
kactivitymanagered.
If it be fixed, KDE said to be without core dump.
