Car won’t start in neutral only in gear

Diamond gear change lights come on and engine cuts out when turning right

I parked the car came out the next day and i have reverse but no forward gears

while i was driving i put it on gear 1 now its stuck on gear1 it doesn't change gears anymore

when i put the car on second gear it gets stuck on 2nd gear

My cars gear is stuck and won't move other than first gear and neutral, what could be the reason
