I'm having a problem with frequent freezing and audio lag, when the game was running completely fine a couple of weeks ago. I've tried updating my drivers, using the lowest settings, disabling fullscreen and switching from Vulkan to DX12, but nothing seems to work. When I tried to run as administrator, I kept having the same pop-up from Rockstar Games Launcher (I own the game on Steam) telling me that I do not own RDR2 on this account. My PC is quite powerful so can run the game on high settings, and I've never had any issues like this in the past.
