Hey I found a solution that worked for me. I have no idea why it worked or what it did or if what I’ve done is safe but here’s how I got it to open up:
I went into the installation folder in Engine\Binaries\Win64 and run UnrealEditor as admin. This worked so I could get into the start up Home Panel.
I created a NewProject and tried launching it. The editor got stuck at 74% again.
I went into the created project file and opened the .uproject with Notepad.
Anything that was under Plugins that was set to true, I set it to false.
After that the Editor and Project launched normally.
I closed the project and went and opened the .uproject again with Notepad and set everything back to true.
It seems to be working fine for now.
Again I have no idea why and I don’t know if it will work for you. If someone can explain why the heck any of this worked I’d be grateful.
In any case, I hope this helps somehow.
I did the below and it fixed it for me - I used 5.6 editor to create a Blank project. (i.e. Games/Blank template). I then went to that uproject, and chose open with and selected 5.7 UnrealEditor. The project loaded ok.
I then went to Epic launcher, and started 5.7, and it worked with no issue.
I’ve got no idea where it’s dragging the list of plugins from - StylusInput is where I was hanging, but it’s clearly not in Engines/Plugins, not can I find it anywhere in config. But the above seems to reset it OK.
I faced the same issue after a fresh installation of epic games & unreal engine 5.7. It automatically installed the fab plugin & Quxel Bridge plugin
what worked for me is uninstalling the Quixel Bridge plugin and then launching again
