Loss of applets

Hello, I am having problems with 2 applets in the thumbnail bar (Fedora 44)

  • sound applet: following error message

what can I do? Note that on my Lenovo X240 laptop (Fedora KDE) no problems

Not speaking English I used a web translator. Sorry for the turns of phrase
Thank you

Après une mise à jour en console, par par discover (Fedora 44), tout refonctionne.
