LT partially works in Libre Office

Greetings,
I am using LibreOffice v.7.6.2.1 (x86-64).
I activated Language tools as outlined herehttps://languagetool.org/insights/post/product-libreoffice/
In LibreOffice LT appears to be working, it underlines errors as it should and gives suggestions for corrections when I right-click on the error.
LT also added a menu item to the LibreOffice Tools menu, as it is supposed to. When I click on the new LT menu item (Tools>LT) it displays several options: New spelling…, check text, Recheck document, Refresh check results, Options, About.
My problem is that none of these menu items seem to work. That is, when I select any item in that menu, nothing happens. No error messages, no pop-up window appear, no nothing.
I stumped on how to proceed, so I thought I would ask for your help. I would like to install ngrams-en-20150817 to LT.
Thanks for your help

I’m using Windows 11
