Unreal Engine's UI laggs

I have resolved the issue like this:

Edit → Project Settings-> UDP Messaging → Untick Enable Transport

Thanks man you are a LEGEND, I spent all day trying to figure it out
worked for unreal 5.0.3

btw this is sad that there is only premium support exclusively for paid license holders, and simple folk like us needs to scrolls forums for all day long just to use their software properly
