PrusaSlicer crashing when slicing but only when initiated from Slice button, not when initiated from Ctrl-R or File ... Slice Now

Odd one this. The title says most of it really.

• This started happening from a previously stable installation, though maybe after Bambo Studio was installed on the same PC. This could be a complete red herring.
• It is limited to one of the two Windows PCs I use.
• I have tried following various uninstall/reinstall procedures, e.g. https://forum.prusa3d.com/forum/prusaslicer/uninstall-completely/ with no effect
• 100% repeatable on 2.9.2 and 2.9.3

Steps to Reproduce

• Start PrusaSlicer just from Start Menu
• Right click on the build plate and Add Shape ... Sphere
• Click on Slice Now
• View changes to the Slice View
• Pop up say "PrusaSlicer has stopped working" and offers Debug and Close Program options
• I choose Debug
• Visual Studio reports "Unhandled exception at 0x00007FFE1C98C000 (nvoglv64.dll) in prusa-slicer.exe: 0xC0000005: Access violation writing location 0x000002351F58B004." and the following call stack, which probably only tells you that it's an OpenGL issue of some sort

nvoglv64.dll!00007ffe1c98c000()
nvoglv64.dll!00007ffe1c985c3a()
nvoglv64.dll!00007ffe1c982acd()

nvoglv64.dll!00007ffe1c3c970a()
nvoglv64.dll!00007ffe1c3c92ce()
nvoglv64.dll!00007ffe1c64a958()
kernel32.dll!00007ffeccfd7374()
ntdll.dll!00007ffece9bcc91()

Note that if I add a Box instead of a Sphere, then there is no crash

And as noted above, if I use Ctrl-R or File ... Slice Now there, is no crash
