At this point you cannot delete the screen nor edit the screen.
Basically your app is frozen and you can only start a new session which is redundant because it puts your app into the same sitution.

Solved! Go to Solution.
I was finally able to delete the screen that was causing the error.
Still not sure why the errror occurred but I was
using the Static Data Connectors to import Excel tables into my app from my hard drive, not dropbox, these were the only data sources,
This app version is following the article https://powerapps.microsoft.com/en-us/tutorials/dev-appsource-test-drive/
The screen that was causing the error only had a Data table and a drop down controls.
No forms.
Thank you AKotb for looking into this.
Thanks for reporting this issue.
Could you please give us more info, what kind of datasource was bound to the form ?
This particular app uses the Static data connector, imported Excel Spreadsheet.
Thank you
Forms Don't support static datasources. (an excell sheet from dropbox connection is not a static datasource)
What other controls do you have in the app ?
Thanks
