New Languagetool Base URL Api connector only works in safe mode

Hi,
I have installed the connector for languagetool in LO 74 as described here and it does work for one language in safe mode both for general use and premium, but not in normal mode.
Can anyone suggest how to debug: i.e. find out wha it is preventing from working in normal mode?
Thaks in advance.

Version: 7.4.2.3 / LibreOffice Community
Build ID: 382eef1f22670f7f4118c8c2dd222ec7ad009daf
CPU threads: 8; OS: Mac OS X 12.6; UI render: default; VCL: osx
Locale: it-IT (it_IT.UTF-8); UI: en-US
Calc: threaded

It seems to be buggy. That should be reported to the developers of LanguageTool.

I’d think that if it works in safe mode, but not in normal mode, then it’s unlikely to be LanguageTool’s problem, but rather LibreOffice one.
