Bug workaround try handler issue?

The script is running from a non-boot volume, under the path /Volumes/Samsung2TB/macOS/installinstallmacos.py ; Here's the console output beginning at the point where I make the release selection for Ventura 13.1:

Hope this is helpful, I tried to check if there were similar reports but didn't see any.
