Unity Android Exporting Problem

Hi everyone! So I downloaded Unity 2021 with the Android support data and that stuff, I just wanted to build my VN game that was generated by Fungus, but when I try to build the game, when it reach "PostProcess" it says that the build failed and it doesn't export the APK or ABB file, and it showed me 2 errors on the console:
(Errors are on the photo)
Is there anyway to fix this error guys? Plz i need help!

 

Start with a new blank project, just save and connect the default scene, make sure that builds correctly.

Don't attempt anything with your actual project until you get the toolchain fully installed and configured according to the docs.

 

I already did that, i created a new empty project and i tried to export and it showed me the same error

 

Then it's definitely some important step missing in your install. I would recommend uninstalling and reinstalling, paying attention to the parts necessary for Android to work: SDK, NDK, Java, etc. Make sure they are all the version recommended for the version of Unity, etc.

Welcome to Android. Welcome to Java. Yes, it's always been that bad.

 

I did! All my programs SDK and JDK and NDK and even Gradle are up to date! I even Installed them from Unity!

 

Well, I fixed my problem by downloading and installing NET.Framework 4.8, when i installed it, everything is back to normal again!
