Hello, mate.
There is a chance that Android Studio lost your JAVA_HOME
Check here Settings => Build, Execution, Deployment => Build Tools => Gradle
Take a look at Gradle JDK field and make sure it's set up correctly, in your case it should be 17 (17 should be in path also, not 19)

@RunRanger did you manage to build your app ultimately ?

As @fudzi9nine said, it seems you were trying to build your app with JDK 19 while it should be JDK 17.
You can run java --version to confirm the JDK version you use.
