After the upgrade to 0.43 this morning newly cloned repositories (several repositories from my students) will not run JUnits. The stack trace I get is:

The project is configured to use JUnit 5.9.1.

Downgrading to version 0.42 resolved this error.

Already-cloned repositories continue to work normally on version 0.43, for what it's worth; it seems to be only newly-cloned ones that fail.
