Post diode mode on the fuse and CC1/2 pins of U3200.

cc1/2 and the fuse ---- open circuit

You MUST check with red probe at ground; black probe on test point.

cc1/2 .......635
fuse ------120

Inspect the pins inside that USB-C port.
Also check continuity from USB port to corresponding CD3215 area.
