Cintiq Pro 16 Constant disconnect and pen issues (possibly driver issue)

Hi! I have a Cintiq Pro 16 and a Windows PC, which have been working fine for most of it's run (about 5 years?). However, in the past year, it's been having a lot of issues that I can't seem to pinpoint.

A lot of disconnecting and reconnecting issues ("Wacom device not found errors" even when plugged in.

There is also fluctuating pen pressure (Wacom pen troubleshooting reads as working, however, Storyboard Pro does not seem to recognize the pen pressure and I have already trouble-shot with them as well, to no avail.

I have already unplugged, restarted, replugged all wires multiple times, I've uninstalled and reinstalled Wacom drivers multiple times as well.

I'm at the end of my rope and would really appreciate some help. Thank you so much!
