PRO version not compatible with Elementor

I upgraded to the PRO version in order to incorporate a Google Drive file upload option on an Elementor Pro form, as described here: https://softlabbd.com/create-file-upload-form-in-elementor/.

Since activating the PRO version, I’m unable to edit any pages unless Elementor is put into safe mode. (When Elementor is put into safe mode, I’m unable to see the “Google Drive Upload” type on my Elementor Pro form.)

Any help is appreciated. Thank you!
