Hey guys, Any help trying to identify what is wrong with this one?

The first layer was pretty flawless except for the top-right side, where it looked kind of grainy. Maybe the plate needed cleaning on that side, but generally the adhesion is solid.

I was away while the second layer was printing, but apparently it failed and it looks like shit. When I got back, it was air-printing, still on the second layer as far as I can tell. However it seems like the nozzle was causing some of the artifacts to form, like maybe it was hitting the first layer or something? I am not sure.

This is on a Bambu A1 mini, with Bambu matte filaments. It is on a brand-new 0.2 nozzle, first print just out of the package. And the reason I got the nozzle was that I had some maybe similar failures before, where my previous nozzle seemed like was showing signs of clogging - i tried some cold and hot pulls, I could do some prints but some where failing so I thought to take this part out of the equation.

Any ideas what maybe could have caused something like this? The filament? I had tried drying it a while ago i believe, I can try again and I got a brand new one as well, but I wouldn't believe so because the first layer seems pretty good at the beginning. Could the plate maybe being dirty have caused buildup of crap on the nozzle and lead to a failure? Could it be something I can try maybe with the Z axis (although I have no experience with this? I did another calibration now though). I had read about AMS tubes as potential reason, but not sure how to tell. Any ideas what to check?

For reference I am trying to print something similar to this in different colors. I have already done 4 prints in other colors successfully.
