In Brush Editing Mode, using the Extrude command will always cause the editor to crash.

In a fresh installation of UE5.5.1 with all settings set to default, the editor crashes every time I use the extrusion command in the brush editing mode of the Geometry Polygon feature. However, this command works fine in UE5.3. I have attached a video and the error message that appears during editing. Please verify this bug.

Update your video drivers and clean out your appdata cache of all your DX shaders. You could also try switching to DX11 and see if it happens using that. I am running a 3080TI and Windows10 Pro and used it for hours the other day and it worked fine.

I did read recently that Windows 11 and some recent patch was causing issues for people.

Still happening in 5.5.3, making UE basically unusable for me right now…
