I got this seam issue does anyone know how to fix this

Probably need more info, include the .3mf if possible, or at least basic settings (IE 0.4mm nozzle using Bambu PLA with stock settings).

With so little info I can only suggest the most basic issue: filament is wet and needs drying.

Yeah sorry about the little info here is the 3MF file
The nozzle 0.4mm Printing in PLA which is dryed so should not be a problem,
also I use the stock PLA settings provided by Bambu

PS this only happens on the corners
