@eed3si9n As mentioned, I run the following without metals locally:

$ sbt
...
sbt:sbtRoot> project utilLogging
...
sbt:Util Logging> testOnly *.ProgressStateSpec

And I get this:

[info] Formatting 1 Scala sources...
[info] Formatting 1 Scala sources...
[error] scalafmt version 2.3.2 classpath is corrupted: /Users/sebalf/dev/sebastian-alfers/sbt/.scalafmt.conf

However when I apply the following it works:

-addSbtPlugin("org.scalameta" % "sbt-scalafmt" % "2.3.0")
+addSbtPlugin("org.scalameta" % "sbt-scalafmt" % "2.4.2")

I can create a separate PR if you think it makes sense but wanted to keep it out of this PR.

Not sure if the failing builds are related to my change.

@sebastian-alfers I think it is tangentially related in a sense that adding additional test has uncovered some weird race condition / initialization issue that was previously not noticed. I have a fix for that, which I tested first on top of this PR to make sure it would fix both - #6557
