I am still getting this error

Just read the error:

Unsupported class file major version 61

=> You are running Gradle with JVM 17, but JVM 17 is only supported by Gradle 7.3+

@Philip W how can I fix that, I am using 7.6 version

Don’t think so, otherwise you would not get the deprecation warning in the first line.

I think it is the other way around
