Why is my mouse lagging the editor?

hi, no third party. i ran a test with only essentials running on windows. still the same.
it happens with my keyboard input too.
So if I’m in editor and tap W repeatedly. i can see spikes on the graph from every tap. this is most strange. and I have been using 5.4 for weeks now. why has this happed? did a windows update break something. nothing new is add to the computer.

I have disabled the plugins which others say was causing similar spikes like the “Studio telemetry” plugin etc as well. still the nothing has changed
