Hi!
I had the exact same problem as Walshie
I found an AsoboReport- Crash.txt document and in it it said there was an error occuring in
C:\Users<your name>\AppData\Local\Microsoft\WindowsApps
the offending prog was python.exe
I deleted it (via command Prompt as an Admin) and it has now started loading (at least)
hope this helps or points in the right direction
