Unable to add avatar as admin

Hello,

We seem to be having a conflict that I’m hoping you can help me sort out. After disabling WP Rocket, we are no longer able to select a user avatar from the media library. When editing a user, clicking on “Choose Image” opens a blank box with no images to select from or buttons.

I can provide access to our dev environment if we can connect over direct email. For now, here is the error that’s showing in the console when accessing the choose image option:
