Arch Linux

You should give more information. How does it fail? Does it not work at all? Is there any error message?

When i click on applet in control panel nothing is happening.
When i type "cinnamon-settings applets" in a terminal there are several python errors.
like this:

That seems pretty broken, so I submitted an upstream PR here: https://github.com/linuxmint/cinnamon/pull/8964

Given that the cinnamon 4.4 ecosystem is in the process of being tagged with lots of interesting changes, I may end up simply waiting until then to apply the fix to our package.

It seems that the problem does not come from cinnamon but from the SpiceUpdate applet.
https://github.com/linuxmint/cinnamon/issues/8956

It's the same problem.
Remove SpiceUpdate by right click on the applet in panel then remove /home/$USER/.local/share/cinnamon/applets/SpicesUpdate@claudiux and it works again.
