The square button doesn't work. Help?

[Android Central Question]

I am using Android 8.1. I don't know what specific type of phone I have, but it's from BLU. I think it's M6. Home button and the back button work just fine. The square button does not. It shows the 'ripple' (can't describe it any better) animation when I click it, so it knows I clicked it, but it does not bring my other apps. It does nothing. Please help.
