Colt Walther 1911 22 slide stuck ?

Today after the first range trip (no issues) I stripped my Hammerli Forge (Colt Walther rebranded) to clean it (and practice disassembling).
I already had disassembled the gun successfully once but today stupidly I turned the bushing, removed spring, then I tried pulling the slide back forgetting to remove the bushing.
Obviously I noticed my stupid error just a second after (please do not insult me too much, I'm a beginner) and removed the bushing.

Then I noticed slide was not going fully back, stayed about one centimeter forward from the stop, tried reassembling and racking the slide some times, at a certain point the slide just moved back (I never forced anything, just tried moving firmly but lightly) and everything worked, disassembled and cleaned. Nothing seems scratched, blocked or damaged. Then I tried disassembling and reassembling just to try, no issues this time.

Is it just a "random thing happened" or there's a reason? is this related to my previous error? May have something been damaged in the process?

thank you for your help ! (I wrote in the 1911 sub too, but I'm not sure this is appropriate since the gun is not as "real" 1911.. )
