Hi there,

I’m just trying to run Unreal Engine 5.4.3 from Ayon, and am getting an error
“Failed to open descriptor…”

anyone know what this is all about?

well, I’m guessing it has to do with the path to the project.

When I mapped the same path to a letter drive, I no longer had the error.

Hopefully this helps someone who has the same issue :slight_smile:

so, the problem has something to do with the UNC paths ?

I think so, but I didn’t get any error relating to that specifically.

But that is a fair assumption
