Application started to build with another .jks himself

I’m trying to upload another version of application to Google Play but I am getting the following error:

You uploaded an APK that is not signed with the upload certificate. You must use the same certificate. The upload certificate has fingerprint:

[ SHA1: bla-bla ]

and the certificate used to sign the APK you uploaded have fingerprint:

[ SHA1: different-bla-bla ]

You need to use a different version code for your APK or Android App Bundle because you already have one with version code 1.

After that I executed the command
exp fetch:android:keystore
and tried to build with this .jks but with no results
How this can be solved?

Also, I have origin .der, .cer with correct SHA-1 but without .jks for that
