I deleted company portal on android and reinstall then signed in again, but now my MS Teams profile is having problem showing 'something went wrong while running the app'.

I then try to sign in to my account using window and it shows 'we couldn't find a Microsoft account. Try entering your details again, or create an account'.

Hi @CHAW XIAO MAN, 

Thank you for posting your question in the Microsoft Q&A forum. I’m glad you reached out.  

From what I can see, the issue started right after the Company Portal app was removed and reinstalled. When this happens unexpectedly, it can break the device’s Primary Refresh Token (PRT). That token is what Microsoft Teams uses to confirm your work identity on Android, so once it gets disrupted, Teams can no longer trust the authentication session. This also explains why Windows now says it can’t find the account, the system is still holding on to an outdated device record that no longer matches your current sign‑in. 

In this kind of situation, the best next step is to ask your IT administrator to remove the old or “stale” device entry from your Microsoft Entra ID. Once that outdated record is cleared, your device can register again cleanly and receive a new PRT, which generally resolves the Teams sign‑in issues. 

For reference, you can share this documentation with your team so they have something to refer to while working through the issue: How to manage stale devices in Microsoft Entra ID - Microsoft Entra ID | Microsoft Learn 

And if they run into any challenges or something doesn’t behave as expected, they can always reach out to Microsoft Support by creating a ticket through the Microsoft 365 admin center for further assistance. 

If you have any updates or more questions, feel free to reply here. I’m happy to help within my scope.

I think ur device still has a bad AAD devc stamp… when Portal is removed out-of-order the PRT chain desyncs and Teams can’t trust the token anymore. ask IT to drop the stale deviceId in Entra and force a fresh PRT regen. that’s the only thing that fixes this cleanly.
