Unreal Engine Editor doesn't start, stays at 0% - Initializing

Development Getting Started & Setup

I think I have figured this out, though of course I’m not sure if it will work in your case.

Be warned, this includes adding an .exe file to your firewall exception.

So I had the same issue as you. Other issues associated with the “Device Association Service” were that Phone Link would not open, I could receive text messages, but not open the interface. Oddly enough, I could not open Unreal Editor either.

For full context, I had just finished a clone, from an older 2.5" SSD to a new PCI-E SSD and I upgraded my Ryzen CPU from 2700x to 5950x.

Steps I took to resolve.

  1. Open ‘msconfig’ and disable the ‘Device Association Service.’
  2. Restart.
  3. Set inbound and outbound firewall rules for DASHost.exe in ‘C:\Windows\System32.’ (allow all connections)
  4. Open ‘msconfig’ and enable ‘Device Association Service.’
  5. Restart.

I can now open Unreal, use the Task Manager and also open the Phone Link app now.

Hope this can assist others.

Given how much stuff this seems to break, this isn’t Epic’s fault, this is quite clearly an issue Microsoft need to resolve.
