Thank you for the bug report!

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), and Plasma 5.27.5 is no longer eligible for support or maintenance from KDE. It's possible that the issue exists only in Debian at this point.

Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.
Thanks for understanding!

Thanks again!

plasmashell (5.27.5) using Qt 5.15.8

This crash has consistantly happened for at least a year. It seems to happen most when trying to open up the app launcher. As other reporters have mentioned with similar bugs, this happens most often after the system is coming back from suspend. It will crash once when the app launcher is launched, or sometimes when the mouse goes over elements in the task bar. Then it doesn't crash again until usually the next day or hours later when returning from suspend. Plasma automatically re-launches after the crash.
