Android IL2CPP error in Unity

I get the following error when Building my application in Unity 2021.2.3f1

 Internal build system error. BuildProgram exited with code -2147024893.
 System.IO.DirectoryNotFoundException: Could not find a part of the path 'C:\Program Files\Unity\Hub\Editor\2021.2.3f1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\�l2cpp\Release\StaticLibs\arm64-v8a\compile.rsp'.

At first the 'il2cpp' in 'C:\Program Files\Unity\Hub\Editor\2021.2.3f1\Editor\Data\PlaybackEngines\AndroidPlayer\Variations\�l2cpp\Release\StaticLibs\arm64-v8a\compile.rsp' I thought it was because of the letter "i" but I'm not sure about that.

Also, while installing on Android SDK 31, I noticed that libraries such as "System.IO" do not work in apk. Google wants minimum 30 sdk to update my apps but I can't even build the app.
