Rabbist VCS stopped showing up

Recently, Rabbit VCS stopped showing up in nautilus. Tried this method and this, no help.

I have Ubuntu 18.04 with GNOME Shell 3.28.4

This is what I get:

RuntimeError: Bad magic number in .pyc file
ERROR   rabbitvcs.services.checkerservice   org.freedesktop.DBus.Error.ServiceUnknown: The name org.google.code.rabbitvcs.RabbitVCS.Checker was not provided by any .service files

    pid = self.status_checker.CheckVersionOrDie(version)
AttributeError: 'NoneType' object has no attribute 'CheckVersionOrDie'

This method also doesn't help. I get:

ERROR   rabbitvcs.services.checkerservice   org.freedesktop.DBus.Error.ServiceUnknown: The name org.google.code.rabbitvcs.RabbitVCS.Checker was not provided by any .service files
    Traceback (most recent call last):

erservice.py", line 265, in _connect_to_checker

Any ideas on how to get it showing up?
