I would really really appreciate some hints on what could be going wrong here!
There’s a copy post here but it seems to have been forgotten https://answers.unrealengine.com/questions/527911/canr-run-build-failed-to-open-descriptor-file-erro.html
Is says this,
I am not able to run my development packaged game over a shared folder. Ie I am trying to run it on a computer that is not itself hosting the packaged directory, but instead using a shared folder structure for the packaged project.
I keep getting this "Failed to open descriptor file. ‘…/…/PROJECTNAME.uproject’ error message.
I have checked both the .exe files and they are correctly named projectname.exe. I see people in other threads being asked to rename these but that will not work for me as they are already correctly named.
Btw, this is a Blueprint only project, no c++.
What do I need to do to be able to run the game?
