Looks like your NVIDIA graphics driver is failing:
2019-01-10T19:10:10 MCEBuddy.AppWrapper.FFmpeg --> [AVHWDeviceContext @ 00000185553e1d80] Failed to create Direct3D device
Possibly it was updated recently, most common issue.
OR I also noticed that there’s no user logged in, although you’re running Win 10 and it should work without a user, but just incase:
2019-01-10T19:10:05 MCEBuddy.AppWrapper.FFmpeg --> Starting process as a UISession process with Admin privileges. This requires atleast 1 user to be logged into the system (remote desktop or locally)
ERROR> 2019-01-10T19:10:05 --> StartAppWithAdminPrivilegesFromNonUISession WTSQueryUserToken failed (No logged on users) with error 1008. An attempt was made to reference a token that does not exist.
WARNING> 2019-01-10T19:10:05 MCEBuddy.AppWrapper.FFmpeg --> Unable to create UI Session process with Admin Privileges from NonUI Session. Is any user logged on?
