I have forgotten my keystore password and I want to install my apk on Google Play. What do I do?

Question

I have made an application and I signed its apk one month ago. Now I have forgotten its password and when I am using a new key for this and installing it on Google Play, it's giving me the fingerprint error. What can I do?

The application link is here.

The error occurs:

Try to find your password here if you are using Gradle 4.0 and above.

1. Switch to project mode.
2. Open your project name folder.
3. Open .gradle folder.
4. Open gradle version folder (here in my case it's 4.4).
5. Open taskHistory folder.
6. Double click on "taskHistory.bin", select open in text editor option.
7. press ctrl+f to open search box and try to find your key (guesswork).

UPDATE:
In gradle 5.4 version the file path has been changed as below: <project>\.gradle\5.4\executionHistory\executionHistory.bin
