Hi Pujitm,
I'll give you a little update on the solution:
1. Uninstall Unraid Connect.
2. Uninstall Theme Engine.
3. Install Unraid Connect.
4. Install Theme Engine.
Following that order, Theme Engine will work again and Unraid Connect will be in its latest version.
The option to revert would be fantastic, just like we have when we update Unraid Core. If something goes wrong, please let me go back to the previous state so as not to destroy my system. In this case, it's an issue and it's aesthetic, but in other updates it may be more of a compromise for those of us who have our Unraid system as the head of our production environment for "documentaries about killer ants and super-fast turtles", always recorded with our 8K camera, of course.
Thanks for your time.
