LanguageTool 5.6 causes LibreOffice Writer to crash

For some weeks now, I experience crashes of LibreOffice Writer 7.2.5 / 7.3.0 when LanguageTool 5.5 / 5.6 is active. The crashes happen shortly after a document has loaded.

I filed a bug here in the LibreOffice bug tracker with detailed information, but I assume that it actually is a bug in LanguageTool causing the crash: 147668 – Writer crashes shortly after loading document with LanguageTool extension active . I also attached a gdb backtrace.log to the bug.

Is this problem already known? Is there any fix? My set-up is quite typical (Ubuntu 21.10 with LibreOffice).

Thank you!
