Unreal freezes on creating blueprint from an Actor

Go for it, but of course it’s only relevant for those who wish to build the engine from source - since this issue appears to affects a lot of new users, they may not wish to go to all the trouble.

So it appears the best solution is to recommend people to do is one of the following:

  • Option 1 (Easy): Set “Asset Editor Open Location” to “Main Window” in Editor Preferences.
  • Option 2 (Easy): Change the Default RHI in Project Settings → Platform → Windows to be something other than DX12, DX11 appears to work.
  • Option 3 (Hard): Build Unreal from source with this patch applied: https://github.com/EpicGames/UnrealEngine/pull/11316
