In the gif, when the FPS stop changing, it means the editor is in non-responsive, no matter it’s in Level Editor, Blueprint Editor, Project Setting… Everything in editor get no response during that time.
This issue has never happened before when I use 5.3.2 or 4.27.2. I have tried disabling UDP message, disabling TCP message, stop sending usage data, disconnecting the netword of my laptop. But nothing works.

Hi there, @AllenYe9!
Would you mind reporting your bug to our team? As 5.4 is a preview build, we want to get any bugs squashed we possibly can before full release, and this might be an edge case we want to make sure doesn’t make it through! The Unreal Engine bug submission form can be found here. When submitting a report, we highly encourage everyone to include images and videos, but any and all details are helpful!
We may reach out if more information is needed.
Thanks!
