SQL Lite: Failed to connect to the database SQLSTATE[HY000] [10]


after a power loss today, I wanted to restart my Nextcloud. (It is running in a Docker)

Unfortunately I get the error message:
“Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [10] disk I/O error in /config/www/nextcloud/lib/private/DB/Connection.php:87”.

I took the experimental version, I think it’s called “SQL Lite”?

I would like to get Nextcloud running again, if possible I would also switch to a MariaDB.
On the Nextcloud was running Talk, so I would be happy if it would work again for now, unfortunately I don’t know where to start.

At the log in line 87 of the Connection.php I get only the expeption function for the error interception
