Short description of error
Extruding a vertex on a sufficiently high poly mesh does not work and can appear to cause small graphical glitches in some cases.
Exact steps for others to reproduce the error
Here's a .blend file with a high poly cube.
#77342 - Extrustion bug.blend
Original steps to reproduce:
Push the E key not work for Blender 2.90 June 3, 2020
Blender 2.83 it work push the E key I can see.

I can confirm the issue, but am having trouble pin pointing the issue.
Here's what I know so far:
I will continue to investigate to see if I can recreate the issue from a simple file or pin point the cause with the current model.
Yes correct. not matter vertex, edge cause problem on 2.90 I was work and make me frustrate start over, start over many times yesterday and today.
When open Blender 2.90 Alpha there cube is fine extruded.
I got download and clean up everything complete and extrude any edge and/or vertex cause bug of 2.90.
I've found the cause, updating the description to reflect this. I will also bisect the issue to find the commit.
Really good job @Alaska

Note that this isn't related to extrude, drawing any loose wire fails in the file provided, unless all faces are deleted (with only faces option).

as the cause.@Jeroen-Bakker, mind taking a look.
Updating the description to include the bisect information.
Oh really. Good job. Thank you for fix correct english. My not good english I do know sign language.
I just test what you said very excellent correct answer yaaa ay.

Push the F key is bug while between from vertex to vertex too.

Comfirm. It could be related to my change. Not sure what the real cause is. as this part is single threaded.
Solves the issue. Means that the split of the mesh_render_data isn't working as expected. Will investigate.
