Proxmox: Nginx Proxy Manager 2.10.1 crashes on upgrade with your script

The subject says it all. Your script is awesome and has worked perfectly for about a year. I just started to install 2.10.1, and the upgrade script throws no errors, but NPM refuses to run. When I check the log, I see the following repeated over and over:

Mar 31 17:27:02 npm systemd[1]: Started Nginx Proxy Manager.

At this point NPM becomes unreachable. I cannot access the GUI and all reverse proxying fails too. The only solution I have found is to roll back to 2.9.22. (I snap the container before the upgrade.)

It seems that other people are having NPM problems too but many of those relate to MySQL. It also seems that permissions can be a challenge and so I am not sure if that is related to this.

TIA!
