Revolution Slider Tinymce Error

Good day,

Revolution slider is causing multiple issues in the admin area for the ONLY THE “shop manager” role.

1- WC order is not showing

2- Custom Post types screens aren’t working.

By deactivating revolution slider all plugins work fine. I have enabled WP-Debug and there is no errors. I have also activated PHP errors, and there is also nothing.

The above screens that should load has a fatal error, some referring to tinymce not loading etc.

Please could you assist with this?

Kind regards
