notes
I don't have a windows machine to tell if the problem is specific to Github action or not. This problem was found when trying to start the sbt launcher against a sbt.version=2.0.0-M4, which causes the runner to use sbtn since #7775.
workaround
Invoking sbt via powershell instead of bash does not trigger sbtn and thus the problem is not visible.
