At schematic C9 is at VBUS and C10 at 3V3 but at PCB it looks different.
Placing all 100n capacitors together has no sense.
If your IC have only 2 VCC supply pins than you probably need only 2 100n capacitors.
It looks that you have GND at bottom but you don’t use it to make your connections.
You can look at one my PCB to compare:
All vias you see there are GND. Compare their number with your 2 GND vias.
And my bottom (blue) GND is continuous - not broken by any tracks. Continuous GND plane gives minimal possible impedance for return current for all signals.
You have 2 tracks USB connection. But in USB signal there are also intentional common mode signals and they need return path (from uC to socked GND pin) but just there you have big break in GND zone. Imagine return signal instead of taking the shortest way have to go around that break.
