I have a big problem with signing my application. I cannot generate a new key.jks. When I do this, I always get an error saving the key. Android Studio and APK Editor Studio are affected. I cannot sign the application in any of these programs. I really don't know how to do this. All descriptions do not provide for the problems I have encountered. Additionally, there is a problem in Android Studio with the Gradle plugin which I cannot update. Attempts to reinstall the program do nothing. Any tips? I am not a programmer and I do everything by trial and error.

keytool -export -rfc -alias upload -file upload_certificate.pem -keystore keystore.jksWindows:
"C:\Program Files\Android\Android Studio\jre\bin\keytool.exe" -export -rfc -alias upload -file "C:\upload_cert.pem" -keystore "C:\keystore_new.jks"
