Not sure my machine will handle 2.81, do you mind if I use 2.80 instead?
It's my graphic card. Blender 2.80 frequently crashes on me. It's good because I'm learning ctrl+s often. :)
I think the issue is related to the Auto Perspective mode in Orbit & Pan settings of the Navigation preferences. I disabled that the other day and so far (fingers crossed) Blender hasn't crashed on me.
