Instax 50s Broken Strip Camera Flashing E (error)

My Fujifilm Instax 50s started flashing E (error). At first, I thought it was the battery, so I replaced those. Nope. Then I thought it was the film, so I replaced that. Nope(wasted a whole pack). I looked online on what it could've been. Someone mentioned to 'restart' the camera, but Turning it on, then pressing the POWER and PHOTO buttons at the SAME TIME. All it did was make a long noise (like it would if it were printing a photo). I looked more into my cameras body, and found a little strip on the left side WASN'T CONNECTED to anything! I'm 100% sure that is the problem, but I don't know how to fix it, or if it's even fixable... PLEASE HELP!
