Unreal engine 5.1 crash at start

Hrm, I have one more known workaround:

Frequent freezes/fps drop in Unreal Engine 5

For others that finds this thread hoping to solve stuttering in Unreal Engine Editor, go to your Project Settings → Plugins → UDP Messaging → EnableTransport (Set this to false). This solved it for me, I had the Editor FPS drop happen in 4.27, 5.0 and 5.1, no content browser up, empty scene and no blueprint windows up. PC specs: 3080Ti, 128GB ram, threadripper CPU (24cores) and so forth. PS: More info, UDP is related to network settings. If you are using a VPN that might cause this issue too…

If that one doesn’t work, I have a couple questions!

Are you on a private network with any kind of tunneling or VPN going on?
