OpenMW has stopped working (2 screen issues)

I used OpenMW for about a month, everything worked perfectly. Suddenly, a few days ago, when launching a game, OpenMW stopped working for no apparent reason. I have 2 screens, I tried using 1 of them, but on a FullHD screen, OpenMW doesn't work anyway (I used to play with it normally). I tried updating drivers and cleaning the system - nothing helps. Also when switching the screen the error:

Error receiving resolutions

SDL_GetNumDisplayModes failed

Video subsystem has not been initialized

P.S. Vanilla Morrowind is working.
