Client failed an anti-cheat runtime integrity check. (1) & (4) Errors

I keep getting the error: "Client failed an anti-cheat runtime integrity check" (specifically errors (1) & (4)), and I need a quick fix. I have already re-downloaded Apex, restarted my PC, updated Windows, and tried every method suggested by AI, YouTube videos, and so on, but nothing works. Please resolve this issue immediately. I purchased the Battle Pass before the anti-cheat changes, and I need to get this fixed because I don't want to lose out on my purchase. Please fix this problem.
