Android Studio 4.1.1 has this bug,
In gradle-wrapper.properties
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-bin.zip
This won't download and always gives 'gradle cache corrupt' error, but a small change makes it work fine
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip
Now sync the gradle again and it's done.
