System UI not working on HTC One M8 topic

Hi, My system UI keeps failing on my HTC One M8, I have no status bar or home button, back button etc appear on my phone!

Version main: 4.16.401.10 and CID Num is: HTC__001

I have done a factory reset, cleared the delvic cache, data cache.

I get two error message when android boots up, HTC Dot View has stopped and another error message, System UI has stopped.

Can anyone help me? Thank you
