Try initially pushing down on back of hood (to momentarily ease force on at least one hood catch) whilst simultaneously operating release lever. It may be there's too much slack in release cable though. See image below of nearside release mechanism and it's adjustment noting this operates in series with offside one which also has similar adjuster. You can gain access to both through spare wheel well and by looking in and up.
