Autoptimize files returning 404

Hello good day!

We are experiencing some issues with Autoptimize, as the autoptimize files are returning 404 on pages, like example
/wp-content/cache/autoptimize/autoptimize_{unique_id}.php

is returning 404.

How do we fix this one? I have deactivated autoptimize for now as the css and js files are not being applied on the site because of the 404 error.

Thanks.
