Failed to transform flutter.jar to match attributes

Question

I am having an issue when I run my flutter app.

* What went wrong:
Execution failed for task ':flutter_appcenter_bundle:compileDebugKotlin'.
> Could not resolve all artifacts for configuration ':flutter_appcenter_bundle:debugCompileClasspath'.
   > Failed to transform flutter.jar to match attributes {artifactType=android-classes, org.gradle.libraryelements=jar, org.gradle.usage=java-runtime}.
      > Execution failed for JetifyTransform: C:\Flutter\bin\cache\artifacts\engine\android-x64\flutter.jar.
         > Failed to transform 'C:\Flutter\bin\cache\artifacts\engine\android-x64\flutter.jar' using Jetifier. Reason: Cannot open a library at 'FileMapping(from=C:\Flutter\bin\cache\artifacts\engine\android-x64\flutter.jar, to=C:\Users\Anton\.gradle\caches\transforms-2\files-2.1\bb1623c867f6cdcbdfa4a85290968351\jetified-flutter.jar)'.

What I have tried to solve the issue.

1. I have reinstalled Flutter.
2. Deleted gradle cache in Users/MyUserName/.gradle/cahce
3. Deleted the whole .gradle folder in Users/MyUserName/.gradle
4. Reinstalled Gradle.
5. Cloned the project again from repo without /build folder.
6. Ran flutter clean.
7. Ran gradle clean.
8. Uninstalled gradle and downgraded to 5.6.4
9. Tried various solutions from stackoverflow from users with a similar problem.
10. Reinstalled Android Studio

I have flutter in my environment variable as well as gradle and 100% its working.

Running my assemble with a stacktrace I get:

❯ gradle assembleQADebug --stacktrace
