Did you find any fixes?

I had this issue as well when migrating a 4.14 project up to 4.18. My project was a C++ project. Deleting everything except the UPROJECT, Config, Content, and Source directories, then re-generating VS files from the UPROJECT fixed the error.

I am now running into the issue in this thread: Error when updating to 4.18 (generating visual studio files) - Platform & Builds - Unreal Engine Forums - however - that seems to just be the next bump in the upgrade road.
