Unable to build watchOS app on Apple Watch via Xcode

I am unable to install my watch app on my Apple Watch via Xcode. There is no code change from my end and this issue just happened recently. My Apple Watch is running on watchOS 7.3. This is the error log I received whenever I tried to build my watchOS app.

System Information
macOS Version 11.2 (Build 20D64)
Xcode 12.4 (17801) (Build 12D4e)
Timestamp: 2021-02-04T00:36:31+08:00


Things I have tried:
  1. Upgrading/downgrading Xcode (version 12.2, 12.3, 12.4 and 12.5 beta)

  2. Deleting "Derived Data" folders

  3. Unpairing/Pairing my Apple Watch

  4. Cleaning the project and restarting XCode

Any help would be greatly appreciated. Thank you!
I am experiencing the same issue! Xcode 12.4.
@khiawyen Can you please file Feedback & post the number here? We'll likely need more info to investigate, and a Feedback is the best way to get that info from you. Thanks!
I think I found it: FB8989096, yes?
Yes that's the correct feedback number. Thanks!

Any updates? I just started getting this error with a watch app that previously built and installed to same watch just fine. Thanks for any help!

Also running into this problem. People on my teams are unable to build our watch app on M1 machines, but those with Intel machines aren't having an issue. Has any progress been made on this?

Having the same problem with Xcode 13.3, M1 MacBookPro..etc. all latest updates on MacBook Pro, iWatch, Xcode etc.
