20V on USB-C input without 3v3_G3H?
That's really strange.
Did you test disconnecting battery?
Are you using original charger?

0.086 is not very low value.
But you can try injecting voltage; may have luck and some chip enter in thermal avalanche.
Start with low voltage and slowly increase, monitoring the temps; IR cam can help a lot.

Be absolutely sure no high-side MOSFET is shorted.
Check on all big coils.
