.APK not uploading to Google Console

I have no idea what’s wrong!
I’ve tried EVERYTHING, please help me. :c

This is my error:

Warning: No -tsa or -tsacert is provided and this jar is not timestamped. Without a timestamp, users may not be able to validate this jar after the signer certificate's expiration date (2043-05-10) or after any future revocation date.

Please help. :c
