never Mind Raf i got it now.
if anyone facing this error .
- close the editor
- open /config/defaultengine.ini
- eg: if you are facing this error :: LogLinker:Error: AddRedirectList((projectdirectory)/Saved/Config/Windows/Engine.ini) found conflicting redirectors for AnimNode_BlendSpace! Old: /Script/AnimGraphRuntime.AnimNode_BlendSpacePlayer, New: AnimNode_BlendSpacePlayer
- use only highighted part
- control +f in the text editor for find tool and search for the highlighted text . and delete the whole line which consists these text . you will find two lines delete both of them.
- Then open the project and you are done .
Thanks Raf .
