I think you need to determine 3 things...
1) What current does the Penta SATA HAT supply via GPIO pins. My bet is 3A, since very few boards have been released to the new HAT+ spec.
2) What current does the WD Green SSD pull.
3) How well supported is the WD Green SSD with your USB/SATA adaptor.
I suspect that you have a combination of power issues and a not fully supported USB/SATA adaptor & SSD combo. The fact that you had issues with the USB C PD supply and just the USB/SATA adaptor connected SSD supports this. Potentially switching to getting power from the HAT just makes things worse.
The "usb_max_current" override flag just tells the Pi to not current limit the USB ports. It does not magically acquire more power. If the HAT is only supplying 3A you may have issues.
I took a quick look at the Radxa site and could not find any specs on supplied (passthrough) power to the Pi nor did I see any claims of being a HAT+ board.
One thought is to switch back to a microSD for the OS for troubleshooting, to eliminate the power draw from the external SSD as a source of your issues.
I tend to use Kingston A400 series for external USB/SATA adaptor connected SSDs, since they have modest power draws, are cheap and typically easily available. They will easily function within a 5V/3A power budget. Also have had great success with a Pimoroni NVMe BASE and NVMe SSDs.
