[...and so on for other cpp files...]
Disabling IWYU in the BuildConfiguration.cs fixes the problem. However this does not sound like a long-term acceptable solution. I’m not sure what the root cause may be, I’m new to unreal engine so if there is a better way of reporting/fixing the issue I’ll gladly learn.
Thanks.
