Whenever I try to run any database-related Artisan command (e.g. migrate, schema:dump), I get an Array to string conversion error:

❯ php artisan migrate

   ErrorException

This seems to come from $connection->tablePrefix being concatenated with various strings, which would mean that, although it's annotated as a string, it's actually being assigned an array at some point. As far as I know, I didn't change anything related to table prefixes (I didn't even know that that was a thing) from the default Laravel Breeze template.
