Dbs XDS45 questions

Forgive me, I’m brand new to 3d2a and 2a as a whole so these might sound very ignorant. I put about 30 rounds through my xds before it stopped chambering a round. The trigger upon pull would reset its position each time and I wasn’t able to take off the slide like I’d normally be able to. I’ve already disassembled the gun and upon inspection the trigger bar and assembly seemed normal but I’m not really sure what I should be looking for. Anyone experience this? Anything I should look for? I checked the printed lower for warping and whatnot but everything seems to be intact like it was before. I’m at a bit of a wall here, any help appreciated. Thanks guys.
