Hi, thanks for sharing this issue.
I've successfully reproduced this problem under the new preview build of VS2022 (17.2.0 preview 1).
The issue appears intermittently, so sometimes it works and sometimes it doesn't. The cause appears to be a change made to the threading model in the VS project system. Essentially, the project system throws a locking exception when critical elements of projects in the system are read, claiming that a read lock is not enough. This looks like a preview bug to me, so I would prefer to avoid implementing messy workarounds in NCrunch before knowing whether MS continue to maintain this behaviour outside of a preview build.
So in short, we can't support this build of VS right now and will monitor the problem. For the time being, please roll back to a non preview build of VS.
