Hatsan Escort 22 Trigger Issues

I&having issues with the hammer not catching the bolt and firing pin correctly. It either catches, but is very light and even manipulating the safety will cause the pin to drop, or it won&catch at all. The rifle was never disassembled prior to this issue starting and no modifications have every been done to this rifle. It worked previously, and was cleaned and stored, and this is what I found the next time we tried to use it. Any suggestions to what might be wrong, or diagrams or videos on how to fully disassemble the bolt assembly would be helpful. Thanks!
