A1 mini wall issue

Hello everyone, I’ve been using my A1 mini printer for about six months, but I’m now encountering some issues with wall quality in my prints. As shown in the photo, the walls are coming out with a poor surface finish.

Usually, when moisture affects extrusion, I notice filament that stops mid-print or nozzle clogs. However, this recent issue seems different, as it is specifically affecting the wall quality. Could anyone help me understand what might be causing this?

Thank you for any advice!
