Halo Reach BackCompat Odd Issue

For the past week or so, my copy of Halo Reach (which I haven’t used for about 6 months) will not allow me to sign in. With one controller active, it bring me up to the sign in screen as if I have 2 controllers active and always puts me in the second slot. After selecting my profile, I try to press OK to enter my password but it does nothing and doesnt let me sign in. I have tried re-installing and deleting my data, but nothing is working. This is all for the backwards compatible version (on disk), and I do want to play Reach Again. Help…?

Xbox 360 or Xbox One?

Xbox One (Original Version, Not the S or X)
