I hope someone can help me

I had the same issue. While reading your logs I noticed that you named your project “ProjectS”. I gave my project the same name, had the same issue. Named it to something other than “ProjectS” and the error went away. Just name it something else.

Really ?! The name of the project f up everything… That’s an interesting lesson thanks
