Oh, maybe you are deleting the Reshade folder, without also deleting D3D11.dll You can see it with Preview file Contents here
www.nexusmods.com/darksouls3/mods/3/?tab=files
That .dll is the one that "injects" Reshade into the game, so if your newer preset was a diff version, like 3.4, it needed a different .dll and shaders
Not sure if you are still getting that memory error. Maybe was related to this
reshade.me/forum/troubleshooting/5616-da...reshade-is-installed
I searched
"dark souls 3" crash site:reshade.me to find some threads like that.
