Base crashes after opening

Good evening
I am unable to use LibreBase - I’m on Windows 11.
I can open the database, but if I then try to open a table, query or other object I get the rotating circle for a long time and the object won’t open.
Thanks

Seems you couldn’t connect to the database. You only could open the Base GUI.

Which database type do you use? Internal HSQLDB? Then have a look if Libreoffice detects the right Java runtime environment: Install the correct JRE - LibreOffice on windows 10 / 11 - The Document Foundation Wiki
