Capacitor build error. Cause: java.nio.file.InvalidPathException: Illegal char <:> at index 38

I've been stuck with problem for the past 2 days. no progress whatsoever.

I tried removing platform. adding platform

gradle version upgrade..

literally everything

I don't even know what's causing the issue.

If it's a plugin issue or a configuration issue or an app icon

these are what i've tried:

1. 
   Removed and re-added android platform (cordova platform rm android && cordova platform add android)
   
   
2. 
   Deleted .gradle/, build/, node_modules/, platforms/ and reinstalled everything
   
   
3. 
   Upgraded Gradle version to 8.11.1 and wrapper distribution to gradle-8.11.1-all.zip
   
   
4. 
   Tried running with:
   
   ./gradlew clean
   ./gradlew assembleDebug --refresh-dependencies --no-daemon
   
   
5. 
   Ensured Android Studio is not in offline mode
   
   
6. 
   Downgraded/Upgraded Capacitor plugins
   
   
7. 
   Verified res/values/strings.xml — no visible typos or special characters
   

FAILURE: Build failed with an exception.
