D1 crashes indefinitely when trying to export database with Virtual Tables (fts5)

### What versions & operating system are you using?

4.19.1

### Please provide a link to a minimal reproduction

_No response_

### Describe the Bug

If you try to export a remote database that has virtual tables on it, the export will fail and the database will become completely inaccessible.

The database will throw an error for any query received and it also won't load in the dashboard.

### Please provide any relevant error logs

✘ [ERROR] D1 Export error: cannot export databases with Virtual Tables (fts5)

And then, for any query received:

D1_ERROR: Currently processing a long-running export.

Comienza en la ruta de exportación de D1 y reproduce una exportación de una base de datos remota que contenga una tabla virtual fts5. Comprueba el error de exportación reportado, los fallos de consultas posteriores y el comportamiento de carga del dashboard; se considera terminado cuando el fallo de exportación ya no deja la base de datos inaccesible.
