If you have downgraded to A9 and the problem persists, then it would point to hardware where you have a loosen USB C port.
Your best bet is to go to Service Centre to get this checked that out.

It is definitely not a charging issue but an issue with USB configuration in Kernel.
Being an Android Developer i know the difference between software bug and Hardware issue.
Seems i won't get solution here,i will debug this issue on my own with kernel logs

krkaran12If you know how kernels work, kernel will contact the USB-C port board, which means something is not initialised when you plug in. When you restart, that extra power boost can initialize the hardware from the motherboard. That's why restarting works.And i say again,if i connect charger and reboot device the charging works fine.

To me, it sounds like the USB-C has either become loosen, a defective USB-C port or a short circuit to the USB port (potentially by having a charger that's plugged in and insert it into USB-C port).
Furthermore, unless your not on the latest firmware, I certainly haven't seen this issue as I use my bottom USB port all the time.

I am sure this is not an hardware issue but related to new USB priority implementation by Asus.
