Running VALORANT in multiple windows?

Question

Windows

In general, it is necessary to make it so that I can play, say, from 1 computer on two accounts at once.
Recently, this was solved by running on behalf of another WINDOWS account.
But RIOT apparently noticed this somehow and fixed it, now if I go from 1 PC on two accounts at once and on both accounts I go into the game, then one of the windows crashes
So, maybe someone will tell you where to dig :(
