Broken movement possibly

I got my first watch kit and followed the instructions up until I had to remove the crown. Struggled around with it until I realized the problem was that the lever wouldn’t go down. When I looked closer it seemed that placement of the lever was blocked by to many other pieces of the movement and couldn’t move. I’m not sure if it came that way or if I accidently moved something and broke it as I was struggling to remove the crown. What should I do and does the movement need to be replaced
