Good afternoon and thanks for response.
I’ve just updated the drivers. Issue is still there. Exact steps how this can re-created:

  1. Create new blank project with no starter content
  2. Create new material
  3. Place the nodes somewhat like this:

  1. Drag a selection around the nodes several times and on one of the mouse releases the mouse the editor crashes with this log:
