Error "cannot find declaration to go to" when editing .odin file and press command-B

When I place the cursor on a core library symbol, e.g. expect_value and I hit command-B I get a popup error cannot find declaration to go to.

This is usually a sign that the Odin standard libraries can't be found in the same directory as the compiler executable. Can you share the directory tree of the path that you set as the SDK path in the project settings?
