Hung up on “Loading…. please wait”

When accessing the “File Manager” UI, the plugin hangs on “Loading…. please wait”

I have uninstalled and reinstalled the plugin but to no avail.

If there’s no fix, I won’t troubleshoot with other plugins because I need all the ones I have, so it’s easier just to find a file manager that works than to replace another plugin that’s already working correctly.

Question is – is there a fix?
