I've set up a Scala project with the metals extension and when importing the the build.sbt, this fails and im provided with the following error message and this metals.log
Failed to connect with build server, no functionality will work. See logs for more details.
metals.log
Due to there only being 30.000 chars allowed and the log being 40.000+ I've shared it via a link.
The short version would be this:

Hopefully someone knows why this happens and how to fix it.
