Endless application.tick and freeze

At my one project Unity suddenly started to freeze in play mode. It stuck at application.tick. I have no idea what is going on. A day ago everything was alright but now when I go into play mode it simply freezes and I have to reset my PC every time. But weirdly if I go into play mode from a different scene and move to this problematic scene, it is ok and there is no freeze at all. I searched google and didn't find anything helpful. Maybe there is a "while" loop or something that is causing the problem but I don't know. I actually did some tests with a script where it checks the quality of the settings in Unity using a "while" loop but I deleted that script. Is there any way in Unity that I can run and find what is causing this endless application.tick and make my PC freeze every time?

Most likely, as you said, a problematic loop or other non-terminating section of code in your scripts. Hard to say more than that without seeing your code. A good place to check would be any recently added or modified code.

 

Ooh, I found an error. It had nothing to do with the "while" loop. I was changing some code and didn't see one additional line which had to be changed also. I feel so relieved now. Anyway, big thanks for the help. It forced me to really check the code to which I didn't pay attention before.
