Problem solved! Follow the github link above to see fieldofview's great fix. Thanks!

Tried adding this to start gcode for your printer? M104 S{material_print_temperature_layer_0}M190 S{material_bed_temperature_layer_0}M109 S{material_print_temperature_layer_0} Although, I like to heat the bed before I probe to factor out thermal expansion - and if my nozzle is pre-heated it can ooze while it travels and dives during probe moves.

I was ABOUT to do just that, but I was not honestly sure if it was github worthy or not. I thought maybe there was something obvious I was missing. So, consider it done! Here is a link to the github: https://github.com/Ultimaker/Cura/issues/10837

DxDiag.txt.logcura 4_11 crash.log I hope these help shed light on the problem. I took the log from 4.11 because I have 4.12 working (with the 4.9 simulation view) right now. I can break 4.12 again if you need to see that as well.

Simulation view is crashing Cura in 4.11 and 4.12. It does not crash 4.10, but the object remains shadowed transparent like it had not been sliced. I copied the simulation view plugin from 4.9 over the 4.12 plugin and that lets me at least see a preview. XRAY mode still works when I disable the plugin from the marketplace. Crashing occurs whether a STL is on the build plate or not, and whether it is sliced or not. I simply can't open the mode. Because of the mention of the extruder settings in the bug report, I suspected it was an issue with my custom printer so I did a clean re-install of 4.12 and selected a default Ultimaker printer. This did not fix the problem. I am now thinking something in 4.10+ is just not playing nice with my graphics card. This machine is using an AMD Radeon HD 6700 (which runs solidworks great). I searched the github and the forums and did not see anyone else having this exact issue. Any insight would be most welcome!
