If we see into the past with light and distance travelling so we can’t see things how they are currently, only how they were in the past; and James Webb took a photo from the beginning of the universe theoretically. But if we are seeing it as it was 13.8 billion years ago is there a possibility that the universe has already ended or possibly ended years and years ago and we just don’t know or understand anything about it ? So we are behind and can’t tell ?

Not the end of the universe as such, but there is certainly the possibility that a catastrophic event has happened somewhere in the universe, but we have no way of detecting it due to the finite speed of light. A gamma-ray burst or a false vacuum decay event could be on its way towards us, and we would have no way of knowing about it until it hit us.
