try this way:

download gradle-6.1.1-all.zip
2.delete all files in this folder c:\user\currentusername\.gradle\wrapper\dists\gradle-6.1.1-all\cfmwm155h49vnt3hynmlrsdst
3.copy zip file into this folder
4.rebuild.

Did you ever find a solution to this? Been stuck with this same error all day. Tried countless things but can’t figure it out.

Ignore the z:\settings.gradle message, it threw me too. Focus on your Java version, I had my project pointed at JDK version 21 by mistake, Unreal & Gradle need version 17 to work properly

Thank yous o much for this, it solve my issue.
After I spent a weekend trying to make this build, you were the only guy to mention this.
