I will be looking into this. thanks for bringing this into our attention
We've noticed the same thing. It breaks the whole admin UI, not just the Commerce part.
The bug is now fixed. We will soon release 14.7.1 which contains the fix. Again, we apologize for the inconvenience
I have a white screen in CMS and Commerce when using Commerce 14.7.0, for Commerce 14.6.0 it works.
Additionaly in console I have 404 for file https://localhost:58059/EPiServer/EPiServer.Commerce.Shell/220.127.116.11/ClientResources/epi-ecf-ui/widgets.js
File is missing in EPiServer.Commerce.Shell.zip
