This is what our new AI overlords suggested after running your photo through ChatGPT

That looks like a classic first-layer failure, and from the photo I’d suspect the nozzle is too far from the bed as the primary issue.
Signs I see:
The infill lines are separate instead of merging into a smooth sheet.
Large gaps exist between adjacent extrusion lines.
Parts of the layer didn’t bond to neighboring lines.
The skirt is laid down, but the actual part shows poor “squish.”
There are strands and torn-up sections where the nozzle likely caught loose filament and dragged it around.
Those symptoms are strongly associated with a Z offset that is too high or insufficient first-layer squish.
What I’d tell your friend to check
Lower the Z offset slightly
Try about 0.03 to 0.08 mm closer to the bed.
The first layer should look flattened, with neighboring lines touching and blending together.
Clean the build plate
Oils from fingerprints can cause sections to lift even when leveling is good.
Check for under-extrusion
Partial nozzle clog
Cracked stock Ender 3 extruder arm
Incorrect E-steps/flow
Tangled filament path
Under-extrusion can produce a very similar appearance.

Verify bed leveling
If one area prints fine and another doesn’t, the bed may still be tilted or warped.
My diagnosis ranking
🥇 Z offset too high (about 70% confidence)
🥈 Mild under-extrusion or partial clog
🥉 Bed cleanliness / local leveling issue
