I’ve searched here for the answer to this problem. I started with Kicad Ver. 5.1.5 and when I tried to view the 3D layout, that window hung on my system. Since then I can’t open any PCB files without PCBNEW only displaying toolbars and a completely white background (No Grid). It eventually pops up on the titlebar that its Not Responding.
I have tired the nightly version posted 12/21/19 and that does the same thing. I have even downgraded to the 5.1.0 version (currently loaded) and am still having the same issue. Prior to loading the 5.1.0 I uninstalled Kicad.
When PCBNew runs I have hit the F9 hotkey to see if I could force it to the Legacy canvas. It failed to switch or was hung and never got the keystroke.
Any help would be greatly appreciate. I will till a response keep trying stuff on my end.
