System.Exception: Framework already initialised

So once again one of our test projects behaves weird.

Test project is net472
Project under test is net462

Everything builds fine.
Processing queue says analysis works fine too.

The error comes on the actual tests being run, displayed in the log window in the processing queue.
What do I do?

Others work fine now. Just the tasks for this project all look like this:

Hi, thanks for sharing this problem.

I think this is a downstream exception. Could you submit a bug report after you've had this happen? The log file may reveal what went wrong further upstream.
