Description

On a geopackage, when running a SQL query, the first query will run fine, but quite soon I will get the error message "SQLite objects created in a thread can only be used in that same thread". It seems a normal select query can be run repetitively, but for example a query creating a trigger, or using transform cannot be run twice in a row. The only way to continue with the SQL query is to close the DB manager and start it again. Let me know if I need to do more tests. I have attached a geo package which shows the problem, but have tried with several others with the same issue.

This might be the same as #20331 - though I can run consecutive 'plain' select statements without the message popping up

This seems also the same issue... actually at the moment no query (even the first one) works on GPKGs in DB Manager #18974-6
