I like this game(single and online) (Red Dead Redemption 2)

Comrades, this problem: the game simply ceased to boot, but if true, then it is loaded and about half an hour, or crashes in the menu, or loads a single game in FPS(to do anything, of course, impossible), and at some point just started to hang during boot. Also in the menu(at startup) loading became longer. Moreover, this problem appeared just a few hours ago, before that the game worked fine. All I can say is that the RAM was loaded on 10-15% more, and in parallel, the game now runs smoothly all the rest of the program(which did not exist, because if you start something with the game, it is, obviously, wildly lag). Thanks in advance for your help.
