I have the same problem. Cura 3.5.0 on Windows 10 crashes when I load any stl file. It also crashes when I select a stl file from the explorer and chose "Open with Cura".
With Cura 3.4.1 on the same machine and with the same settings, everything worked fine.
My printer is a Creality Ender 2, it is connected via OctoPrint on a Raspberry Pi. I have installed add-ons to directly open .scad files, for a Z distance and for OctoPrint.
I attach my stderr.log and my configs.
I would appreciate any help!
