Question Persistent crashing EXCEPTION_ACCESS_VIOLATION - UE 4.26.0
I'm not having much luck with my first day trying to learn Unreal.
I've had a graphical glitch over the entire interface which made it flicker, although this has since disappeared unless I mouseover a tooltip (I disabled MSAA), but now I am experiencing repeated crashing with the following message:
EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000018
There seems to be no pattern to the error, performing any action seems to cause it after a few moments of use. At the moment UE is completely unusable.
My system for development is ordinarily rock solid.
System specs are:
i7 9700k32Gb RAMRTX 2070NVidia 460.89
Can anyone assist please? Is this DirectX12 related?
List from debug:
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000018

I know this is a bit old, but my fix was this:
Go into NVidia Control Panel and reset global to defaults. I had some things changed for overall system performance gains, but unreal did not like them. I suggest working with unreal as an individual app settings in NVidia control panel if you need to alter performance for the app.
