So I searched the forum and found this issue from a few years back:
I currently face the same issue on Windows 11 (Version 10.0.22621.2428), Nvidia driver 537, I disabled all overlays but the issue persists.
I stumbled across this GitHub repo:
https://github.com/zzsort/Aion-Version-Dll
Which promises a solution, but I have to launch Aion.bin with custom parameters.
Is there any way to pass these arguments through to aion.bin from the launcher? Can it be added? Or is there some other solution, since downgrading my GPU driver to some ancient version from two years ago is obviously not a solution.
