Weird artifacts around screen in shape of a circle, both on VR and on monitor when playing in VR mode

[D.A.S.I.1]

After I prepared my project for GPU lightmass, meaning, enabling ray-tracing, virtual textures and Targeted RHIs > Default RHI: DirectX 12, I got some weird artifacts around the screen in play mode, both on VR headset and on the monitor, as you see on screenshots, does anyone have any idea why could that be?
Thanks!
