Suddenly project is crashing on startup

My project suddenly started to crash on startup.
I was doing everything just fine, i closed the project and went to the gym. when i got back home and tried to open the project it started to crash on startup.
I think it’s worth saying that i deleted some stuff that were referenced by other objects, however, i closed and re-opened the project around 5 times normally after that, no problem.

This is the crash log(i think) : [Crashlog][1]

A print screen of the crash screen:

Hi Ivan de Souza,

I looked up your crash data and found this bug has been fixed in UE4.14. (UE-34370). I suggest downloading UE4.14 and opening a COPY of your project in UE4.14, not overwriting the original, and only after making a back up of your project somewhere outside of the Unreal Projects folder.

Let me know if this does not resolve your issue.

Thanks,

.

Updating to 4.14.3 seems to have solved the problem, thanks .
