PCBNEW shows only white screen then eventually Shows as not responding

In Kicad configuration directory there is a file named pcbnew with no extension. Open it with text editor, find line like

canvas_type=1

and try different values there from 0 to 2. Close kicad completely before changing the value and saving that file.
0 is legacy canvas (no hardware acceleration)
1 is modern open gl canvas
2 is modern fallback canvas

Most likely you have some issues with opengl not working.
