Hi there,
suddenly, after a weird pc crash that had inhibits the system to reinstall the software for few times even after many reboots (but always suddenly, it got fine without any apparent reason), I cannot see anymore hdmi input from my external camera through my Blackmagic ultrastudio express. OBS recognize blackmagic hardware but shows a green screen with some glitch effects.
Nothing has been modified since the first crash and with the same setup I did many webcasting without problems.
What can be happened?


P.S. hdmi, pc connection and blackmagic card work fine, with other software I can see from my camera.
