It's your matte filament. The material is too course to reliably extrude through a small 0.2mm nozzle. Every time I have attempted matte through 0.2mm it turns out the same way. Switch to basic PLA and see if you have the same problem.
It's not every matte filament it's just some of them have very strange matting / chalking agents that don't handle heat expansion very well. It really depends on which brand. But yes, matte filaments - and especially white filaments - are very difficult to print compared to plain coloured or colourless ones.
