When I open the storyboard, I see a message at the top of Interface Builder that says "An internal error occurred. Editing functionality may be limited".

https://1drv.ms/u/s!AooJiM96YK-_7yBiXXRDyppLAZnHWhen I click on the small round button to report the bug to Apple, a Finder window is opened with a folder selected with the name "IB-agent-diagnostics_2019-06-22_07-29-33_388000" in a folder called "T". In the pane on the left that shows errors, I see an error in gray. I copied and pasted it below:
.../Main.storyboard: notice: Discouraged Configuration: Value other than autosizing specified for width (System items, other than fixed spaces, should use autosizing)
I ran the project in iPhone Simulator. It seems to be running ok.
Is there a way for me to open one of the project files using a text editor and change the value specified in that last error message above in order to correct the problem?
I keep getting a backup of the project and opening it to see if I have the same problem. The answer is yes.
Another time the view controller windows don't have anything in them. They are just blank.

Here is what Interface Builder looked like before, like I described in the original post.

I started having this problem since I started using Microsoft Visual Studio. I wonder if that affected Xcode somehow. Visual Studio uses Xcode.
