This app failed to launch because of an issue with its license

Question

I'm happily in the middle of coding then I try to launch my app in debug mode but I get this error message.

Unable to activate Windows Store app

This app failed to launch because of an issue with its license

The app was launching fine a few minutes earlier so this came as a surprise. I tried restarting Visual Studio but doing so did not help.

I got the annoying "renew your developer license" dialog yesterday I think. It had renewed without issue.

How do I make this error message go away so i can debug my app?

Answer 1

Well, I got it working by deleting the main project's 'bin' and 'obj' folders. Cleaning and Rebuilding wasn't enough. Hope this answer saves someone else the few minutes of confusion I just experienced.

Answer 2

I recently had a similar issue. In my case I had to uninstall the re-install the app to get it working.

Hope this helps someone. Also, to find out further detail about why it failed, you can checkout the event logs:

Event Viewer > Applications and Services logs > Microsoft > Windows > Aps > Microsoft-Windows-TWinUI/Operational

There might be some more detail in there. In my case it was logged as an error event which said the app could not be launched because of a temporary issue with its license.
