Premiere Pro 15.0 uses 100% CPU and hangs or crashes when generating thumbnails

[danm32376722]

I had to revert back to 14.9

15.0 would cause my system (threadripper 2950x and 64GB of ram) to use 100% CPU while it was generating thumbnails and then it would hang on 100% usage and make my computer unresponsive until either it caused a BSOD or I was able to force quit.

Able to repoduce the issue at will. 

Imported the same footage into 14.9 and 0 issues. 

Can provide video of the issue occuring if needed.

Same issue here with Threadripper 3960x.
