The last answer is correct. Well, the newly updated 11.0.0 launcher’s problem is with the GPU. If you have a dedicated GPU, it will try to run on the GPU, which is possibly causing problem. If you have a laptop, or a Desktop with integrated GPU, Go to Advanced Graphics Settings and set Epic games launcher and unreal engine launcher from the installation path to use the integrated GPU. Since it can’t use it run apps, it should run on the CPU, which may help, while other applications, including the Unreal Engine, should be able to use the dedicated GPU. Epic Games must be aware of it.
