Tests sometimes fail with "IllegalStateException: The component was not created"

[rfc2822]

Sometimes, tests randomly fail with:

at.bitfire.davdroid.sync.SyncManagerTest > testPerformSync_503RetryAfter_DelaySeconds[virtual] FAILED 
	java.lang.IllegalStateException: The component was not created. Check that you have added the HiltAndroidRule.

Usually this happens in testPerformSync_503RetryAfter_DelaySeconds, but only in a few percent of the runs and I think sometimes at other locations/during other tests.

Re-running the failed test usually succeeds.

Still happens (davx5):
