This looks like either underextrusion causing gaps in the surface, or the filament sticking to the nozzle a little too much and tearing as the nozzle passes over it.
Simple things first:
check that the extruder clamp screw (that holds the filament against the extruder drive gear) is still tight - it's possible that the filament is just not being pressed against the extruder drive, allowing it to slip
is your nozzle clean on the outside? or does it have a clump of plastic buildup on it? if there's plastic stuck on the outside of the nozzle, the extruded plastic may be sticking to it and tearing
is this a filament that you've used on this printer before? have you done a temperature tower? have you done a flow rate calibration?
do you have more pictures of your test prints? other angles?
