for me it was I deleted a plugin from the engine and using it in my project
For me it was trying to build it in Visual Studio instead using the Live Coding way, Ctrl+Alt+F11
If you had opened Unreal Editor Plz Close And Try Again Maybe Work.
I have a same problem. Do you resolve this error???
I found out that in my case it was related to a plugin “AccuRig”. When it is activated it generates this error. I deactivated the Plugin and now ue / Lyra is working.
Change in LyraStarterGame.uproject the following lines:
from True to false.
This resolved my issue, maybe your issue is related to same plugin or other. Check LyraStarterGame.ueproject which plugin are activated /deactivated. I would deactivate all thirdparty plugins.
Hope it solves for you, kind regards,
Ivan
