Build Failing because of Gradle

Hi! So I just finished my game some days ago and I managed to put it on Google Play and I found out a bug that I must fix. So did I, I fixed it and when I was ready to build and publish the new version I got some error like :
FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:launcher:packageRelease’.

A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
com.android.ide.common.signing.KeytoolException: Failed to read key hexaroll from store “E:\Unity Projects\HexaRollRemaster\user.keystore”: Cannot recover key

  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

  • Get more help at https://help.gradle.org

BUILD FAILED in 13s
Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF-8

Or like this :
Starting a Gradle Daemon, 1 incompatible and 2 stopped Daemons could not be reused, use --status for details

Configure project :launcher
WARNING: The option setting ‘android.enableR8=false’ is deprecated.
It will be removed in version 5.0 of the Android Gradle plugin.
You will no longer be able to disable R8

So… If anyone has any ideas on how I can build the game it would be much appreciated! Also if you need more info just let me know!
