Flutter+Hive应用发布至Play Store遇签名不匹配安装错误

我已将名为moneyreminder的Flutter应用通过Google Play Console发布至Play Store，该应用使用Hive实现本地数据存储，但数据存储模块无法正常工作。同时在Android Studio中运行release模式时出现安装错误：

adb: failed to install C:\Users\Niklas\StudioProjects\moneyreminder\build\app\outputs\flutter-apk\app.apk: Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE: Package com.muellerniklas.moneyreminder signatures do not match previously installed version; ignoring!]
