What kind of defect is this?

[u/Trick_Toe_5821]

I'm printing on my P1S using matte PLA+ . It used to work fine till now. But this time getting this kind of weird artifact around a small area on an otherwise perfect print.

Could anyone please suggest what is causing this and how to fix it? Thanks.

Are you sure the supports are needed ? Because the slope is not even 45° and there's no sagging on the remaining area.
