mc_dec_hevc.dll

In the past 2 hours, I am trying to work! 

Premiere suddenly hangs and closes as soon as I open the premiere project file. And Its happening in various files. 

I checked the event viewer and all the crashing errors are point to mc_dec_hevc.dll. 

what is this and why is this happening all of a sudden?
