Grammar check not working for Italian on new install

I’ve been using LanguageTool for Italian with Trados Studio 2021 for years (also with older versions).
On a clean install from this week (everything at default settings) the app and the plugin work perfectly fine for everything except they’ve stopped checking grammar.
Can you help?

This add-on is not developed by the LT team, so I suggest you contact the developer. You can find their contact information at https://appstore.sdl.com/language/app/languagetool-grammar-and-spell-checker/725/ (bottom of the page)
