Vive cosmos elite black screen with image artifacts

[MMavl128]

Hi,  i bought vive cosmos elite and 3 days cant get it to work. At first i was getting errors 210 and 200 with no image and red led. i've submitted a bug report(# 20210912121539). today i've installed a beta version  VIVE Software 2.0.18.5 and it fixed errors, but HMD shows me a bad picture with more artifacts(like bad pixels in your lcd display). How can i fix it? My graphic card: amd r9 200 series with latest drivers for him
