Recolor 04/24/2023 update error on Windows 2.1.49 dc80804a

Problem description

No idea what happened, it was working fine for a bit after the update. It then suddenly stopped working when I restarted today. The Recolor toolbar up top is gone and the theme reverted back to default, original Anki grey. I cannot update my Anki to newer releases due to the conflicts with other add-ons.

Checklist

[x] I've restarted Anki to see if it helps
[x] I've verified that I use the latest version of the add-on by redownloading it from AnkiWeb
[x] I've tried to disable other add-ons to see if there are any interactions present
[ ] My issue disappears when I hold shift while starting Anki.
[x] I've checked if anyone else reported this problem before by looking through the issue reports. I also checked to see if there is a section about known issues in the add-on description, documentation, or README.

What Anki version are you using?

*Please open Anki, go to Help → About (windows) or Anki → About Anki (mac) to find the version. Edit the value between the backticks below
