What’s happening?
Customers are experiencing issues with Dynamics applications failing to load, displaying error messages such as “We are experiencing some errors while trying to load the application” and “Application failed to load - failed to fetch.” Some users also encounter the message “This app stopped working. Try refreshing your browser” along with a session ID when opening the application in a browser.

Reason:
These application load failures may be due to network connectivity issues, app-specific configurations, or defects within the application itself. In several cases, the issue was isolated to specific applications rather than being part of a broader service outage.
 

Resolution:
For general application load failures:

  • Confirm that there are no network disruptions affecting access to Dynamics applications.
  • If network issues are suspected, coordinate with the network team to ensure that traffic to required endpoints (e.g., runtime-app.powerapps.com) is not blocked or filtered.
  • If the issue began after a recent app update, consider downgrading the authoring version in the development environment to a previous stable version.
For the error message “This app stopped working”:
  • Review the app’s configuration and logic to identify any specific formulas or controls that may be triggering the error.
  • Address any problematic formulas—particularly those that may pass blank values where non-blank values are expected.
  • Capture network traces during app editing or execution and document the session ID to assist with deeper troubleshooting.
Next steps if unresolved:
  • If the issue is identified as a product defect, monitor communications for bug fix deployment and re-test the application once updates are released.
  • If the problem persists after these steps, escalate the issue to the product team for further investigation and resolution.
