Is this still your case: BSSP370smbb_nonLU
If so, I see this in your CaseStatus:
2022-06-22 23:52:28: case.run error
Cannot call rmtree on a symbolic link
I'm not exactly sure what this means, but I had noticed that your pointer files were symbolic links to another directory, so maybe it is related to that.
You could try copying over the necessary files from your REFCASE manually, instead of setting GET_REFCASE to TRUE.
I did this and ran the model for a brief time.
