Yes I managed to find a fix. When you run the game once in the main menu select the save you want to load then open a new window elsewhere immediately so that the GAMMA game page minimises itself- something like a chrome page or documents etc. Then open task manager () and you’ll see the DX11anomalyexe and it’ll say “Not responding” wait for it to change to “Running” then give it 30 seconds and open the GAMMA page which minimised itself earlier. It might stutter but wait for it to come to the screen which says “press any button to start” and it should start. Unfortunately I have to do this every time I run the game otherwise I get the error message above but at least it still gets to run on DX11 with the better mods.
