    Issue

    The problem is that I used a locally generated signed APK, and when I tried to update the app from the Play Store, it caused an error.

    Solution

    Download the universal APK from Google Play Console and the app is able to update normally from Play Store.

    Step to get the Universal APK from Google Play Console

    Google Play Console > Select your App > select Production tab on the side bar > Releases > View release details > Under App bundle section, select the arrow on the right end > select Download tab > Signed, universal APK (download this APK)

    Signed, universal APK

    I think you have a signing key mismatch here.
    As I understand it, you generate a release APK locally and sign it with your signing key.

    You then install the APK locally. Afterwards you go to your app’s Google Play Store page and try to download the newer app update which you also signed with the same key and uploaded as an Android App Bundle.

    I believe the problem is that when you enabled Play App Signing, you did not provide your own signing key as the signing key for Play Store.

    Usually, Google Play Store will automatically generate it’s own signing key unless you explicitly tell it not to do so. It will use your previous key only as an upload key. The goal of the upload key is to verfiy that your uploaded AAB is from you. When the Play Console generates APKs from the AAB it will however use it’s own signing key.

    You can check which key is actually used in the Google Play Console. Go to your app’s Play Console page, select "App Integrity" in the "Setup" category. On the right side, select the "App Signing" tab.

    Now you will see the signatures of the actually signing key that is used by Google Play Console.
