Skirmish Game Crash

Hello

I've encountered a bug in the first/second mission of skirmish. Once I enter the barracks inside the base, instead of going to the loading screen like usual, a windows error pops up and says that the .exe file isn't working. Not sure if I'm the only one who has experienced the bug or not but if anybody could clear me up on this that would be greatly appreciated.

Thank you for your time

This is actually an unexpected bug that seem to be happening from the Unreal Engine, which is from Epic Games' side. How often does this bug occur?
