As a lot of people have already reported, Unreal is crashing on all its versions when using Nvidia drivers 461+. Probaly it’s a Nvidia issue, but I think you could urge them to solve this issue, please; it’s been happening for some months already…
In my case, when using any UE version, with ray tracing enabled (not tested without it, but maybe too), Unreal crashes after some minutes opened, when using any of the 461 drivers. When rolling back to 460, it’s fine.
But, for example, to be able to use the DLSS, you need 461 drivers, so this is a nightmare!
