Unable to create users. Could not locate metadata file: StandardEinsteinActivityCapturePsl-1.uld.xml

I just got word that this is a Salesforce issue around permission sets. New users in our org get the “Skuid Page Viewer” permission set by default and that code is causing this to fail (while referencing Skuid in the error). 

We are unable to access permission sets and get a “Salesforce has been notified” error when we attempt to do so.
