Currently there's a dependency on Metaconfig 9.x.x, but due to this issue, a newer version is available which vendors the underlying pprint library, which recently went through binary-incompatible changes.

What this means is that right now, scalafmt isn't usable in a context where centralized dependency management & resolution requires putting the latest version of pprint into the classpath. Updating the dependency should be sufficient to solve this problem (and would merit a bug report to metaconfig if this isn't the case).

Requesting an update to dependency version and publish with that change (ideally backported to 3.3.x latest release).

Thank you! 😍
