A1 Mini filament doesn't seem to stick after first layers

I have an A1 mini. I already did a few prints that turned out fine, but recently I’m having this issue:

the first few layers seem fine, but after that, it seems the infill doesn’t stick and begins creating a mess, or nothing sticks and makes a mess. But the first ones do stick to the plate.

I’m printing generic PLA using a 0.2 nozzle and mostly default settings. I have run full calibrations. I have printed some significantly bigger and more complex stuff before and it turned out perfect, so I don’t know why all of a sudden I can’t seem to be able to print a cube. I’m halfway through my first spool.

If it’s relevant, I had some issue before with lines, but it turns out I hadn’t secured the nozzle properly, and after I did everything seemed to work perfectly until now. Also, it’s gotten pretty hot here in summer, so in the room there’s likely 30+ C°

Any advice? Let me know if I left out some important info that could be relevant, I’m pretty new to this

That looks like damp filament. Did you try drying it?

How are you cleaning your build plate? Oils from your hands are the most common cause of adhesion issues.

I never dried it before, and it’s pretty hot and humid currently so I guess it could be it. I tried last night to dry it. After searching a bit on how to do it, I ended up leaving the spool covered overnight on the print bed at around 45 C° and with a dehumidifier running nearby.
Tried printing again today. The basic cube worked better. It still has issues, but at least it got printed.


I then tried to print some miniatures, but they failed like this


Do you think it’s due to wet filament? The fact that at least the cube printed, while before it wouldn’t even do that suggests that my attempt at drying at least did something.

I also have another spool which is still sealed. Do you think it’s worth trying that, to see if it prints well? That could confirm there’s something wrong in my current spool, whether wetness or anything else

Yes, I usually clean it with dish soap and dry with a towel, avoiding touching it on the flat surfaces. The filament does stick to the bed, so I don’t think this is the cause of the issue.
My attempt at drying the filament per @CoolUser123456 suggestion did something (see my response to him above this), so maybe that’s the direction to go?
