I was trying to load an old project which got stuck at 39% and 100% cpu. I killed the unreal editor task and then when into the project folder and renamed the ‘Config’ directory to ‘Config_old’ Assuming this would cause the editor to use the base config from the 4.24 engine install directory and not the project settings. I was then able to open the project. Looks like the setting r.AllowGlobalClipPlane=True in project Config\DefaultEngine.ini causing the problem in this case.
