can someone please help, newbie here and definitely still learning. I am printing a model with a round base. the infill is adaptive cubic. The next layer covers the infill fine but then the layer after that it does this and I have no idea why. The filament has been dried well, the achine is callibrated, the build plate is clean. Is it speed thats the issue?

First time creating a model. It may not be perfect but be kind, I've only been 3D printing for 3 weeks.

suggestions needed I bought a P1S and have been 3D printing for 5 days now so a complete novice. Ive done plenty of research but am aware I know very little. I have been printing in PLA and PETG and all has worked fine. today i went to print in the same PETG I was yesterday and it will not stick to the plate no matter what and ends up like the image. I have swapped STL to see if it was that, no. I have cleaner the textured PEI plate thoroughly. Still nothing. I have thoroughly dried the PETG and it has been secured in the AMS2 pro since. I had an issue with humidity at first so printed the ams desicant boxes and took my humidity down to 13%. I have printed PLA since to see if its all filament and maybe the hotend, it prints fine but a tiny amount of stringing (like 1 or two strings in the whole print). Im at a bit of a loss on what it could be. Any suggestions would be much appreciated.
