Hello,
I am using UE4 4.21 and the engine keeps crashing for actually no reason.
- It crashes when I save
- It crashes when I use a widget blueprint for the main menu
- It crashes when I go somewhere else, like my web browser, without touching nothing.
- It crashes directly after I restart it after a crash.
The game has already other assets such as a vehicle with materials and some blueprints similar to this tutorial and its props Using Splines & Spline Components | Live Training | Unreal Engine - YouTube
Also the game shows a Lighting error which is Lighting needs to be rebuilt
