alright once last try , delete intermediate folder, saved , build and binary folders “make sure you make a backup of your folder first "
and if using visual studio 2017 you may need to delete this as well .vs"your project name”\v15\ipch\AutoPCH
Then right click on your porject and select Generate visual studio files .
then start the engine and let it to recompile , then do one test build and see .
Thats what I would do if Im in the same situation as u. hope that will help.
let me know anyway if that works for you or not.
