Can't use Patchbox modules at all

Hi all. Trying to get Patchbox set up on a Pi 4B. I have it up & running and I have output on my USB interface (an Expert Sleepers ES9 module) but I can’t get modules working.

Step 1, I ran the apt-get update script listed elsewhere on this forum, did the system update, rebooted then ran patchbox and selected the puredata module. Result was this:

/etc/amidiminder.rules -> None
Traceback (most recent call last):
  File "/usr/bin/patchbox", line 33, in <module>
    sys.exit(load_entry_point('patchbox-cli==1.4.0', 'console_scripts', 'patchbox')())

Step 2, I tried selecting the modep module. Everything seemed to work fine, no console errors, I get dumped back at the prompt. I figure I just need to reboot and it will drop me into modep like the docs say. I reboot but I’m just back at the desktop like before & it doesn’t even appear to have installed modep. No difference visible whatsoever.

So one incomprehensible error, one nothing at all. Does anyone have another suggestion?

Ah I got modep working - url localhost worked. But it’s certainly not starting up automatically like the “kiosk” experience I was expecting. Any thoughts on how I can fix this?
