So I recently got an EMG STI/TTI JW3 2011 Combat Master and it had been firing fine, so today when I tried firing again (now with a tracer attached if it matters), the slide started to have problems.
Whenever I would fire (both with bbs and without) it would fire but then the slide wouldn't go back forward (

Another thing is, this problem doesn't happen when I lean the pistol to the side (

This problem also only happens when I have a magazine inside the pistol, and I have tried 2 other identical magazines but the same problem occurs (I have also made sure the magazines were filled with green gas) When I don't have a magazine in, the slide slides just fine without getting stuck.
Although the videos I added don't show the actual firing of bbs, the exact same problem occurs when firing a bb. It fires, goes back, then gets stuck.
Why is this happening? It was firing fine for the past few days and is pretty much brand new. What can I do to fix this? If you need more pictures or videos of the problem lmk.
P.S. I'm kind of a newbie at airsoft pistols so please explain thoroughly.
