Error during Android packaging for distribution

Hello, I have a probleme when I package my game.

I specify that when I did the packaging without the “for distribution” option, it worked well. Also I specified the key store with android studio. Thanks in advance for your response.

Certainly something wrong in your signing process.

“Critical-Tower Defense.jks”: Invalid keystore format”

My signing keys are .keystore files. I would revisit the docs here : Signing Android Projects for Release on the Google Play Store with Unreal Engine | Unreal Engine 5.2 Documentation

I followed this tutorial and it’s the same problem.

Ok, not sure what the issue is in that case. Make sure the docs you read match your engine version. I would restart the process once more from scratch to sanity check.
