While trying to create a C++ actor to test if it can be created with a custom Copyright notice specified in Project Settings, the Live Coding window returns a "Build failed" and error of:
"ERROR: Unable to patch action graph - unexpected executable in compile action (C:\Program Files (x86)\Windows Kits\10\bin\10.0.20348.0\x64\rc.exe)"
Visual Studio 2019 also pops open a window stating that the project has been modified outside the environment and offers options to reload or ignore. (See attached.)
Result: The live coding window will return a "Build Failed" in red and an error just above that line.
Expected Result: The class is built without error.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-145201 in the post.
