It seems Rocky 9 has picked a very specific version of tcsh that has this bug. We are pondering some options. You can wait for Rocky 9 to update to a more recent version, downgrade to an older version or use a completely different version. If your administrator allows replacement of the tcsh with a working, non-buggy version in /bin/tcsh, then it's simpler. If not, it's more tedious but possible to do this update as done in this prior thread:
