What's going on with the game?????? (Fallout: New Vegas)

Hello everyone, just recently I discovered that the game absolutely does not obey me and does whatever it wants. It is thrown by corpses as it wants and wherever it wants, often does not exit the VAITS aiming mode, then does not want to read modifications even if they are connected through the launcher and other methods, and spits out the modifications that went to it earlier, according to the requirements of the mods, I watched everything, I have everything I need is present, well, no, she doesn’t obey at all, and recently created a topic about the lack of modifications with companions and armor, but now she doesn’t want to accept anything at all, I hope someone can answer and help, thanks for your attention !!!
