Constant Crashes of Unreal Engine

I just bought a Razer Blade 15 base Version with the GTX 1060 Max Q, and a view weeks ago Unreal Engine started crashing and nothing seems to help. I already checked online, but the version of Unreal (4.21.2) is actually stable. I rolled back the graphics cards driver but after doing so I couldn't open Geforce Eperience anymore and I still had crashes after a bit of time. I also reinstalled windows but after a few days, same issue. I am really confused as to why this could happen. The Projects I'm working on aren't heavy or anything. If anyone has the same problem or just has some ideas what I could check out, please let me know.
