Local AEM instance (Start page) suddenly rendering strangely

[Codelime]

My local Start page is rendering like this (see screenshot below). It seemed to have happened after pulling from master, creating new local branch, and checking out local branch, which is something I do routinely. Any ideas on what happened and what I could check? These are the errors I'm getting:

@Codelime Did you check the permissions? also you can try clientlib rebuild- http://localhost:4502/libs/granite/ui/content/dumplibs.rebuild.html?invalidate=true
