Open any database file. Go to "Queries" → "Create Query in Design View …" Create a query and test this query and run this query (Edit → Run Query [F5]) in design view. There is no content shown in the query. This bug happens every time in LO 7.1.0.1 on OpenSUSE 15.2 64bit rpm Linux.
On pc Debian x86-64 with master sources updated today, I could reproduce this. No specific logs on console.
Also the query works because once saved, if we double click query to execute it, the result displays well.
