@ - Yes, you’re right, our project name is different than the folder name. Updating fixed that error.
Unfortunately I’m now getting the same ‘descriptor file’ error that has reported above. I did manage to fix it by comparing the generated GameDir functionality on Win64 and noticed that the ‘CheckLocal’ and CheckGame’ variables in FGenericPlatformMisc::GameDir() should probably be the same. On UWP the ‘CheckLocal’ variable seems to have an erroneous additional Appx folder in it’s path (two in a row). By hardcoding a fix there, and thus setting my GameDir to LocalGameDir, I was able to get past the uproject load error. Unfortunately I then hit a path failure in one of my plugins. I can provide more detail if required, but it appears that pathing on the current UWP build isn’t quite correct just yet.
