Do you have the powermat quick circle case and a PMA charger? I know this is a dumb question but its not qi its PMA.
If that's not the issue did you uninstall apps or just freeze them? Also were any of them system apps?
I can upload any system app you need since I have a D850 as well just let me know.
For starters you should NEVER put system apps on the SD card unless its a backup. Running system apps of a SD card always leads to issue for various reasons. I would put them back on your phones internal storage. I'm not entirely sure which one is used for wireless charging, but I would definitely put the system apps back on your phone.
