Can't use the app. – Tubex - Videos and Music for YouTube Review

Don't get me wrong, I've been using this app for years and it's my favorite app on my phone, but here's the problem. When opening the app, I'm told that my Google account isn't fully linked with my YouTube account, and it brings me to a create channel page. When I exit out of that, the app instantly crashes. Please fix this! It makes the app unusable!
