Bug Android build only fails when signed for Release

Hello, I'm having an issue where my Android build only succeeds if it is signed with debug. As soon as I use a custom keystore I get "A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade See the console for details." and when I enable Release in player settings under Minify I get "
java.io.IOException: Can't read
(Unsupported version number [55.0] (maximum 54.0, Java 10) See the console for details." Does anybody know why this is happening?

 

I fixed it by unchecking release and I used Split Application Binary, but now I have a issue saying "Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again. Your App Bundle is expected to be signed with the certificate with fingerprint" in the play store how do I use android's default signing without using my own?

EDIT: So, what i'm asking now, is there a way to allow the keys managed by google play to work?

 

The issue is one of the files has been compiled with a version of java not supported by the version of proguard being used in the gradle file.

You can change the dependancy by:
1- export your project
2 - load it up with android studio
3 - modify gradle with the following:
