I am still having this issue. Ryujinx loads fine on its own when I load directly, without any error, but I keep getting this error about windows being out of date when I launch through Launchbox. I am on windows 21H2 build 19044.1682 so I am definitely past 1803 build.
This is driving me crazy guys any help please? I have tried changing location of Ryujinx, but I still receive the error in Launchbox, but not when I load directly. I have tried running in Admin and non Admin mode.
Thanks for any help
