I put battery’s in but the flash will not turn on. (This is the 9)

I have a Instax Mini 9 that I am having problems with. I have tried putting battery’s in it but the light for the flash never turns on so I am unable to take pictures at all. I also had the problem where the battery’s died mid print but instead of it being slightly ejected in top, it never ejected at all. I attempted to remove the film (I do not care what is on it) but it is stuck in the camera. At the moment I am unable to use it and would like to fix that.
