I am new to UE. Created blank project with open world scene, added one Metahuman and few megascan objects to it. Havent done anything with blueprints and I dont think I have really modified anything. Just played with few objects in a simple scene, learning basics of how to move objects, etc. First time, the crash happened in editor. After that it let me in again. I played a bit more, closed the engine and next time I tried to run it, it crashes on startup every time when I click “launch UE5”.
What is happening and how to fix it? Is this usual in UE? Just switched from Unity and this is kinda disappointing. Please help.
