It should be looking at that file from /libraries/gantry5/assets/css folder. Do you have some other component that is also using Whoops?

You can likely work around the issue by copying the file from my location into /libraries/gantry5/vendor/filp/whoops/src/Whoops/Resources, but the fix needs to be applied every time you update Gantry.
