Google Play Console - How remove an update of published application

Click on Create Release Like you release a new version, but instead of uploading an apk click "Add From Library", Here you will get all the previous versions of your app, select the version you want to rollback to, then release it after review button.

In previous versions of Google Developer Console this could be possible unpublising the last .apk and enable to production your desired version

but now it can´t be possible.

Note that rollbacks aren’t supported due to the app versioning requirements of the Android platform. If you need to rollback, consider launching a previous APK with a new version number. However, this practice should be used only as a last resort, as users will lose access to new features and your old app may not be forward-compatible with your server changes or data formats, so be sure to run alpha and beta tests of your updates.

You can see the previous releases but you can´t enable again:

You need to create and publish a new release with a consecutive versionCode.

Just build old app version with new versionCode and old versionName and publish it
