What account were you trying to sign into when you got that message?

Log.in account or some would call it User Account in Windows. Basically when you have multiple user accounts on your laptop or desktop, you would be asked which account to log.in to. One account of mine somehow got corrupted.

How come you could log in via Trust Wallet and not by the original account? Were you logging into the same place?

After one provides their seed phrases on their Trust Wallet, they will be logged in indefinitely there unless they remove the said address.

I can use my mobile Trust Wallet just fine (send tokens via BSC network or stake and unstake on pools and dens) but I can only do this when I am on mobile. On desktop, I cannot do anything since I cannot get into my metamask because I don't know about my seed phrases.

So I decided to just create another BSC address so I can again use both mobile and pc. :)
