Default [Q] ATT Converted GPE Camera/Wifi don't work after 4.4.3 OTA

I converted my AT&T HTC One M8 to GPE a month or two ago. It has been working great, until yesterday when I applied the 4.4.3 OTA update straight from Google. Now the camara doesn't work "Can't connect to camera", and WIFI won't turn on.

Has anyone else had this problem? Should I have never done the OTA update? I thought once I converted to GPE it was the same as a GPE phone.

Thank you in advance for any help.
