Musescore 4.2.2 can't use MuseSounds

Crashed and rebooted after opening the latest version of Muse Hub and was unable to open it. Downloaded MuseSounds after reinstalling the last version of Muse Hub, it shows grey in Musescore and cannot be enabled. Also can't find the MuseSounds section in the mixer.

Change the folder in Muse Hub to re-download MuseSounds or the plugin, i.e. the following pop-up appears. Uninstalling and reinstalling Muse Hub does not fix the problem.
