Photoshop not working with Huion H640P

The Problem:

Photoshop does not work with my drawing tablet as intended. Originally, I had a pressure sensitivity issue where I could draw but sensitivity would not work. I was able to get the warning triangle to go away by doing the UserConfig trick, however after that, my pen would not work with the brush tools and similar ones (not allowing me to do any strokes or anything), however works fine with normal tools a pen tablet wouldnt be need for (Bucket, Eye Dropper, Wand etc.). I have my shape dynamics set to pen pressure and enabled the targets at the top. I not sure what else to do, my drivers are up to date and my tablet works fine in other paint applications.

What I've done (note I rebooted PS after doing each thing):

Updated drivers

UserConfig trick

Enabled Windows Ink

Disabled Windows Ink

Reg Fix in windows

Restarted computer

Switched USB Ports

Anyone have any ideas on how to fix this?

Additional Information:

-Tablet is not a display tablet.

-OS = Win 10, up to date.
