Hi , erayozgur.
Cloning is kind of difficult because to clone your computer, like your entire profile, it can take up to hours or days unless someone has access to your computer and made a copy of the system, maybe it's difficult but not impossible.
More likely to have occurred the remote access while you were not at your computer or accessed your accounts individually the problem could have occurred on the smartphone as well.
More to reduce the chance and better disable automatic login like steam and epic activates all 2FA systems and removes passwords recorded in browsers because if your Google (chrome) or Microsoft (Edge) account is accessed, your password is saved in your profile and also some 2FA have full verification mode using email instead of Smatphone example epic has this option.
Keep windows up to date always check your ativirus analysis every week, I recommend using malwaresbytes free analysis to look for spyware on your computer, check installed programs have MSRT from microsoft to check for malicious software on your windows at the link below:

https://support.microsoft.com/en-us/windows/kee...
Change all passwords that have been accessed and update the security settings of your microsoft accounts and among others.
I suggest you check your smartphone to see if you don't have any suspicious programs that can confirm 2FA even though it's difficult.
