Emergency help with loading a level

I have a strange problem in my project. When I click on a specific button to load a level, sometimes(10%) the game hangs.
I have tested this on several computers but the result is the same.
My deadline is near, and I have to solve this problem. Can someone please help me?


Thanks in advance

 

I think we'll need a bit more information. What kind of troubleshooting have you done? Can you reproduce the problem in a simple project? What does the log say? The first thing to do narrow it down - start turning things off until the problem goes away, then when you've identified the problem script, start putting debug/print statements in to see where it breaks. Most common source of hangs for me are null reference exceptions, which are usually easy to fix...

 

Thanks for quick reply, I have filled that part with lots of debug logs, but as soon as pressing the button the game hangs, and nothing have been loged.

My project is very big , with lots of models and textures.

I had the same problem before, again on pressing a button, but not for loading a scene. But that problem solved by slightly changing the order of the pressing function. and did not understand the problem.

About null reference problem, How can I check that without log?

 

As I say, to fix the problem, you've got to identify it first, so try to isolate it by turning things off until the problem goes away, and/or make a new, simple scene and add your scripts until the problem returns.
