The build of the project does not match the project itself

Hi all. I need your help, because my head is about to explode:
The game was first made on personal, recently purchased Plus. Made a build of the game and dropped it into STEAM for testing (through steamSDK). Made changes to load the scene, changed the animations, build again and it is different from what is in the editor, the build is exactly the same as it was before, the one that I poured in steam. At the same time shows in the game, which is not even in the editor, I deleted it.
Deleted folder Library, did not help. Re-entered my account, did rebuild several times - did not help. Thought that maybe the problem in Steam, maybe it overrides and opens the project that is in the folder SDK, removed from the folder SDK project, disconnected steam - did not help.

What’s the problem?

Dumb answer maybe but you have checked what scenes are included in the build menu? Maybe you have different scenes saved with the new changes

Problem solved. I do not know what caused it, but everything I changed after that build was not accepted, I changed the animation, and it played the old, in short nonsense. Some scripts stopped working, I just uninstalled and re-installed and everything worked.
