This seems to be the same crash as bug 473955 and bug 469440 (although these happen in different applications/widgets). Going by the information in that report, this is an upstream issue, and given that we haven't seen any duplicates in a while, likely fixed in newer versions of Qt.

Note that lattedock is currently essentially unmaintained and has not been updated to use Qt 6 or KF6/Plasma 6; it will not benefit from the upstream fix until a port is complete..
