My editor crashes continuously. It crashes at random times, for random actions (such as right clicking to open menus). Now I cannot hit Play anymore since it crashes immediately every time I do it.
I have been using UE for just a week, and I am currently handle a very simple project. I have less than 20 objects in the world and just a couple of C++ classes with almost no code in them.
I tried to delete temporary files and regenerate VS project files multiple times. I tried to delete data from AppData folder, but nothing changed.
I am on a dell xps 15 9570 with an integrated card and a gtx 1050 Ti. Windows 10. Not a lot of free space on disk (9 GB remaining). 16 GB ram. Nvidia drivers up to date.
I’ve had problems in the past with my Nvidia gpu (which I still couldn’t figure out thanks to a terrible assistance), therefore I am usually avoiding to use it when playing heavy games. For Unreal, I am on Optimus (which I guess should make UE use the gtx card) since I don’t know exactly how to make my computer use just the integrated card for Unreal (I don’t know exactly on which executable to set it).
From my crash logs, I paste here some snippets which may give hints on possible crashes reasons (I wasn’t able to solve the problem myself with this information):
