To Reproduce

1. Generated an AAB file using command ionic cordova build android --release
2. New file created successfully, named aab-release.aab
3. Run the following command: java -jar .\bundletool.jar build-apks --bundle=app-release.aab --output=./app-signed.apks --ks=C:/keystore/location/my.keystore --ks-key-alias=alias_name
4. I’m prompted to enter the password for the keystore, enter the correct keystore password
5. Hit Return, nothing happens for about 20s

Expected behavior Generated an APKS file with some sort of successful message on the console.

Known workaround N/A

Environment: Windows 10

This should be fixed in the latest version.
