Signed android apk crashes but debug does not

Ive tried to create signed version of my apk. I want to put on Play Store, but when i try to open my signed apk version it crashes on start. But in browser, and debug version apk are working totally fine.

I followed this instruction:

And everything passed fine. No erros, but still cant manage to build working signed app.
What can be the problem ?

Any news about this?
I am also experiencing the same problem. And followed the same instructions.

Any update to this? I’m currently facing the same problem
