Do I need to do something after system update (i.e., kernel)?

[HubKing]

I had set it working, and today I found that it wasn't working. When ran the GUI, it disappeared at launch. I started it in the terminal to see the output and it was

Traceback (most recent call last):
  File "/usr/bin/input-remapper-control", line 30, in <module>
    from inputremapper.logger import logger, update_verbosity, log_info
ModuleNotFoundError: No module named 'inputremapper'

It was installed from AUR, so simply uninstalled it and reinstalled it, and then it worked again. I hadn't done anything since the last time it worked, so I wonder why it stopped working on its own. Is it because of kernel update or something? Do I have to something to keep it working?

PS: Come to think of it, the Python version was recently updated (version 0.1 up). Does that have something to do with this?
