Gaps in top layer with bambu PLA

Hi all,

Since 1 week I got some problems with my top layer. Doesn‘t matter which filament I choose. There are always some gaps in the top layer, sometimes more, sometimes less.

I use P1S with standard PLA profile and only PLA from Bambulab.

2 weeks everything worked fine. Can someone help me with this?

Thank you in advance!
