I am a Microsoft Technical Specialist for Business Applications. I am hoping to demonstrate Robotic Process Automation in Power Automate Desktop with the Contoso Invoicing App (https://learn.microsoft.com/en-us/training/modules/install-required-software-online-workshop/install-app). The app worked last year when I tried, but I now get an exception message (attached) when trying to run the app 365161026-a04e6b49-418b-48af-8dcd-1c86ceb8bd01.jpg

Look at the Excel file that is created to hold the information - located under your user profile \ Documents \ Contoso Invoicing.
For me, when I opened this file, it got marked as confidential, so the app could no longer open it. Change the Sensitivity to public and Contoso Invoicing should open again.
