Strange warning, VS can't be open due to modal operation

Hi guys,

Ever sicne upgrading to the latest version of UE4 and VS 2017, I keep getting this error in my console whenever I try to open a source file:

It will also take several minutes for the “Loading Visual Studio…” message in the bottom right corner to disappear. What’s weird is that even though this error is shown in my console, the file will still open up and let me edit it as normal, however when UE4 catches up, it will load another unmodified version of my file, sometimes two or three times, so I’ll then have multiple instances of VS open at once. Is anyone else experiencing this strange behavior?

I am running UE4 4.18.3, and VS 2017 15.5.5. Any pointers would be great!

I have this issue as well. No resolution yet???

I had the same issue using UE 4.18.3 and VS 2017 ver 15.2. I used to get errors whenever I tried to build the project in VS, but doing a clean and rebuild the project seems to fix it.
