So, after some search, I found some fix online. When I first created project, I had Substance Plugin enabled. But I disabled it when I moved to 4.14 preview. So I installed it to 4.14 and enabled it.(It gave me same error when disabled.) That solved this issue but I had another issue where on packaging stage it would give me another error. AutomationTool: Couldn’t update resource. So another search online. I found these two:
I checked my intermediate folder and my folders were read only too. And even though I made them not read only they would go back to read only. I couldnt use his solution because I dont use c++ and dont have git version so I look for a faster way.
This is when I had lightbulb in my brain :). He problaly didnt realize that zipping project wont zip intermediate and some other folders. So I deleted my intermediate folder. And woala! I packaged it.
