Answer 1

finally found the problem it was my antivirus that was restricting AAPT to execute and make change in protected folder

1. Disable File Safeguard
2. Allow AAPT to Execute

Answer 2

Try a clean build:

flutter clean

Then try running on another device:

flutter run -d DeviceName --release

If you do not need to debug, but you still need logs then a release configuration or a profile config should work for you --profile
