Ultimate Member Upload File Function Broken

I’m using the premium version of ultimate member and have added an “Image upload” and “File upload” section for the users. Whenever one of these buttons are clicked, the webpage gets greyed out and a broken “upload” popup shows up at the bottom of the page half cutoff.

Nothing is clickable and there is no way to upload, the page has to be refreshed.

The error message on the browser shows:

Uncaught TypeError: r.uploadFile is not a um-functions.min.js?ver=2.3.1:1 function 
    at initImageUpload_UM (um-functions.min.js?ver=2.3.1:1:2706)
    at um_new_modal (um-functions.min.js?ver=2.3.1:1:9392)
    at HTMLAnchorElement.<anonymous> (um-modal.min.js?ver=2.3.1:1:5263)
    at HTMLBodyElement.dispatch (jquery.min.js?ver=3.6.0:2:43064)
    at HTMLBodyElement.v.handle (jquery.min.js?ver=3.6.0:2:41048)

The profile page is definitely setup correctly as other fields/information for the user can be edited/saved.

My WordPress & plugin is up to date.
I’ve tried in incognito browser.

Not sure what to do to fix this…
If I uninstall the plugin and reinstall, will it delete all my forms/settings etc?
