Media Encoder 14.xx Crashing while creating proxies from Premier Pro.....

Media Encoder crashes about half way through the second or third file before it hangs up.  Shut down ME and then send the ones that havent been encoded yet.  Again about the second or third one it crashes again...any ideas....My computer specs...Processor AMD Ryzen 9 3900x 12-core 3.79 GHz  64 GB Ram OS and programs on 1TB SSD and the GPU is a Nvidia 1070.
