scala-steward-action: Scala-steward execution hangs at refresh cache of target repo

When I try to run scala-steward against another repo, GHA execution always hangs at the following spot. I have seen a similar closed issue, where there is a problem with cache in self-hosted runners, but this is happening even though the runner is not self hosted. Action logs are as follows:

✓ Coursier installed, version: 2.0.16 ✓ Github Token provided as input ✓ User information retrieved from Github ✓ Github Repository set to: myreponame. ✓ Scala Steward workspace created ✓ scalafmt installed, version: scalafmt 3.0.7 Launching org.scala-steward:scala-steward-core_2.13:0.12.0 2021-10-27 09:43:12,963 INFO

and from here on, it keeps on running indefinitely, without any progress. I need to cancel the runner for the Action to stop. When I don’t set github-repository then it’s running against the repo where scala-steward action is installed, and it’s working, but when target is different repo, it hangs. Here is my workflow file:
