Ask HN: How to navigate USB-C charging hell

There's classic USB (5V @ 0.5A) which is supported by every USB port and USB Power Delivery (USB-PD) which can negotiate power up to 240W. Your phone may require PD to charge but none of the ports on your PC provide PD thus it doesn't charge. USB-PD used to be really expensive and now it's still expensive so maybe only Apple supports outgoing PD from their computers.

Then there's proprietary charging protocols like Qualcomm Quick Charge that I hope are being phased out.

Later versions of Qualcomm quick charge are compatible with USB-PD and USB-PD-With-PPS respectively. PPS is programmable power supply which some phones like Samsung need for ultra fast charging.

My motherboard port are USB 3.2 which should support USB PD. But it is part of the things I cannot get confirmation of.

My phone used to charge fine on my old motherboard.

You should give the motherboard model. There usually are tweaks in the bios for charging that might need to be set.

BIOS or Software issues? You should try other devices to see if your MB are charging those as well.
