Insecure filter warning

Big Sur 11.6.1

Deleted all the printers (in Library folder and also in User’s folder).

Run install.command and then … ‘insecure filter warning’ (in Print Tool triangle symbol with exclamation mark) - unable to print.

See screenshots.

Anny idea?

It’s OK - I removed and reinstalled QTR, Print Tool and Piezography.
