UE4 Crash when I'm trying to play

Hi everyone ,
So when I want to test my game , I usually click on play , it’s simple.
But since a few weeks , when I click on play , my project crash and I can do nothing on the software , so I need to shut down UE4 with the task center of windows.
I noticed that this happen on only 1 project , and it seems like the bug appear since I have created a flipbook 2d , I don’t know what I can do.

Recreate the flip book or find the error within that Blueprint, not much else can be done otherwise. you could also go to File → cook content for windows, and see what warnings/errors come up in the Log output.

First, post any relevant log files. You can find the right ones by referring to
