Sorry to hear you're having trouble.
I had done some research on zapret-discord-youtube and see that it's bypass engine designed to circumvent ISP blocks. If the system works for you when you're using that then it may be that your ISP is blocked from accessing the service for some reason. You may want to look into that on your end by contacting your ISP to find out.
As for your account not working please try following the instructions to use the Sign In Helper via this link https://support.microsoft.com/accounts-billing/manage/microsoft-account-sign-in-helper to see if you're about access the account from there. Once completed please keep an eye on your email including the junk/spam folder for a response.
