Installation stuck on 'processing'

Installed brand new 1.10.1 Stable Diffusion and when I try to install facechain, the webpage just displays 'procession' and never moves ahead of it. I can see the facechain directory created under /extension/ but the 'processing' message never goes away. 

I've waited upwards of 10 minutes. The command window shows no errors. When I refresh, the facechain tab does not appear in the UI either.
