Open Link/File (Alt+O) does not work and throw errors

[unifreak]

I'm on Ubuntu 22.10 and using Sublime Text 4143. Alt-O is triggering switch_file command, so I have to manually run plaintask's command via command palate, but this has no effect and trigger errors inside the console. Here is the trackback:

Traceback (most recent call last):
