According to dump, it crashes during call to:

�� 0x21d8c8 I NBWndClassEx class>unregister:instance: 0x10f7e7cc: a(n) NBWndClassEx class

the reason could be that you passing wrong handle which not exists (or was existed in previous image session but invalid now).

Not much else i can say without having image and trying myself.

NBWin32GLContextDriver>>supportsCurrentPlatform
�� ^ NativeBoost platformId = NativeBoostConstants win32PlatformId

Then, trying the following Roassal3D example produces a VM crash:

R3Example new city

Attached is the crash.dmp file. Currently, we are using an old pharo image for developing Roassal3D under windows.
