Somehow adding Image broke my project

I was making project for weeks,
But when i added just two icons into the game(Which i made)
Game freezes when i press play button in editor
Even when i build the game and execute the standalone file, It freezes
I deleted the file and tried again, but it didn’t worked at all

I was making whole dot graphics on my own
and none of them made this issue
the file name was “PS_NEW.png” is anything wrong with it?

Is there any solution that i can try?

Hard to help you with these brief descriptions.

What I would do: Did you try debuging it? Add logging at several Start() methods to see which Start() or Enable() method is still called.

Next, do you use version control? Try to go back to the situation that it works and mimmic the changes you made in smaller steps to see if it breaks.

Did you remove the .asset file while removing the .png?
