Restart your pc, refresh the BPs.

I have a feeling it might help to delete your config and intermediate folder as well but don’t take my word for it. But I recall reading something like that when I had a similar problem. Either way, IF you do it, backup your files

Very thank your reply,bu it’s useless… Last few lines is below in the Cook-2017.03.10-16.12.52.txt ,but i cann’t find some useful information.
