Keystore issues...

So I have a Play Store app that had a specific keystore set up. It randomly stopped working so I set up a new keystore, made sure I have the correct passwords, and requested a reset through the play store.

After requesting by generating the certificate (which requires correct passwords), I went to build my app and got this error:

Execution failed for task ':launcher:packageRelease'.
> A failure occurred while executing com.android.build.gradle.tasks.PackageAndroidArtifact$IncrementalSplitterRunnable
   > com.android.ide.common.signing.KeytoolException: Failed to read key rc from store "C:\Users\BigBrain\Documents\UnityKeystore\rc.keystore": Get Key failed: Given final block not properly padded. Such issues can arise if a bad key is used during decryption.

Any idea what might be causing keystore issues when I know it’s the correct password?


Edit to add info:
When it initially stopped working I copied the project and reset it by deleting everything except the “Assets” and “Packages” folders.

Secondary update: It’s definitely the keystore because the project builds just fine when I turn off Custom Keystore
