Answer 1

It's an access-related issue. You can try to check this link with your browser https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/7.2.2/gradle-7.2.2.pom
you can see that there is an error, and it's not accessible for you.
And there are multiple ways to gain access.
Here is an old answer of mine explaining how to set up a valid connection.
You can also use some VPNs like ProtonVPN, which will have a system-wide effect.
