When i lauch engine it just crash any ideas how to fix this?

Are you launching a project or just the engine itself?

if youre launching a project, try removing saved and intermediate in the project folder( Dont delete them, you might need them for backup later).

When i launch the engine from epic games laucher i just get crash reporter please help me fix this

I had this problem once, I’d suggest you to try other versions of UE4 like 4.18 or 17

When i click launch in epic games laucher so its engine itself

I’ll see if someone has the answer but this is probably the only solution so if noone knows how to fix this I’ll just intall other version thx

Dosent work it cant initialize after 45%
