Cause
This issue is often caused by your protocol handlers not being configured correctly. Refer to Understanding protocol handlers - Win32 apps | Microsoft Learn (external link) for information.
Resolution
Navigate to your Windows Settings → Apps → Default apps → Choose default apps by protocol and check the configuration for HTTP and HTTPS.

- If a browser is not assigned for either of these protocols, assign a browser and try again.
- If a browser is assigned, try assigning a different browser and trying again. If the browser launches properly and guides you through the OAuth authentication process, this indicates that there was an issue with the browser you were previously using.
