Adding the system plugin directory fixes that, but only when the two Qt builds are the same version: loading a plugin built against a different Qt would crash rather than look wrong. + + So a system Qt patch bump silently unthemes the app until the venv is + updated to match: the versions differ, this returns early, and the + window comes up in Fusion with no error anywhere.
