Use JDK 19 (or anything below 20)
Configure your Gradle version by looking up Gradle Compatibility Matrix

In case you're using JDK 19, go for Gradle 7.6

Go to %USERPROFILE% (Which is usually C:/Users/<your windows username>)
Delete the .gradle folder (you can also delete the .android folder)

Now go to your project root folder > android > gradle > wrapper > gradle-wrapper.properties

Change the distributionUrl as https\://services.gradle.org/distributions/gradle-7.6-all.zip (Check your Gradle version first and replace 7.6 with your suitable version, if you're not using JDK 19)
