Hey! I’m using 4.22.1. I’m trying to package my game into IOS platform and I’m getting “Failed to open descriptor file…/…/…/ProjectName/ProjectName.uproject For troubleshooting, please go to docs.unrealengine.com/latest/INT/Platforms/iOS/GettingStarted/index.html” message. I’m trying to package my game on Launch button with development provision and certificate. Unfortunately I’m getting this error too often. Sometimes it working when I deleted the Saved and Intermediate folders but not always. Something is wrong with this. I’m looking for a permanent solution for this annoying error. I couldn’t find a good solution on answerhub / forums or search engines. Thank you!
I am having the same issue. Has anyone found a lasting solution to this?
I’ve been fighting this for years now and it still rears it’s ugly head. I too would love to find a permanent solution.
Same issue here…
This happened to me when I updated Unreal Engine (to 5.6, but it doesn’t really matter) and after the update, I deleted all my intermediate and build folders to do a complete rebuild. I then wanted to try to run on iOS device but forgot to package the project 
So I first packaged the project, then re-run it and the error was no longer there. I’m guessing it has to do with some assets / built files not being available when the game wants to run.
