Edit: Solved by manually deleing all local files.

Hello, I've tried to launch the game after the last update and it's stopped functioning properly. It's launching for few minutes and then Ui appears with very low fps with black background. After trying to load a save file, I can hear sound but there is only black screen with only hands visible. I've tried to update Windows, GPU drivers and verified integrity of Alyx and Steam VR. Also, removed GPU drivers with DDU. I've tried few other VR titles and all are running smooth as before. I have RTX 2080 Super and Steam Index. I've recorded an issue: https://www.youtube.com/watch?v=XbjBHKyMWmc

Please advice what can I do. Steam Support was unhelpful so far.

Edit: In my case it have been resoulution multiplayer set to maximum for Alyx specifically and it caused to fail video initialization. I was sure I didn't change it, but it has been changed somehow so try to check in SteamVR how is it set per application.
