There is a new version of the SDK using unity. This version is deprecated in iOS 14. There are HelloWorlds for the new version. See below.
See this thread on StackOverflow: https://stackoverflow.com/questions/64051081/ios-14-google-cardboard-view-is-broken
And this thread on Github: https://github.com/googlevr/cardboard/issues/118#issuecomment-698565712
I would like to link the Google Developers page, but apple does not let you post links from developers.google, but its down this path: /cardboard/develop/unity/quickstart
TLDR;
update to new unity sdk
