There's a good chance this will fix #19320. My problem is that without a lot of added boilerplate I cannot test it, since it's hard to have at the same time external dependencies and ad-hoc instrumentation in the compiler. But what I could observe from the minimized example, it searches for a conversion of Concurrent[F[_]] to NoType and that must have caused the blowup.

In any case, the change makes obvious sense, so let's add that and see whether it improves things.

Published it locally, Metals picked it up and it's indeed fixed! Thank you very much @odersky ! 🎉

Btw. as a side note to test it in Metals, you only need to do sbt publishLocal on dotty and change the version in the using directive. No need to tinker with releasing Metals locally.

I think this should go into LTS as well.
