Android Studio, Flutter no “sign and release APK / Bundle” button

  android-studio, build, dart, keystore

Good day to everyone, the point is … Previously, to simplify my life, I always used the Build button in AS in order to sign and release the application release. Now I bought a new PC, dragged the source code and after starting the project in AS and even after creating new projects in AS, the items in the menu disappeared
enter image description here

Maybe I didn’t take into account something when I set up Flutter and AS?

What screenshots should I send?

I have no desire to create keys with -keytool.

Thanks in advance
