Are you on Windows and your Anki version is 2.1.33? If there’s an error message, could you attach it or take a screenshot? What do you mean by “the program crashes”? It’s no longer responding or it’s something else?
Maybe update your graphics card driver.
Maybe install “Video Fix 1” - https://ankiweb.net/shared/info/1006287781
Maybe try to update mpv to the latest mpv version. Please see the last part of my reply here - Anki crashes because of MPV
