Ah, my apologies! We can log into Cloud orgs once we have permission, but in your case (On Premise), an app export would work as well. App exports don't include query data, so exporting your app with a HAR file would be particularly helpful. If you're not interested, then no worries at all.
Your current app seems a bit more complex than our usual apps that we debug over text, so perhaps coming to an Office Hours session sometime in the coming weeks could be enlightening!
Or if you have any specific questions/error messages, happy to continue trying to troubleshoot here
