Would add /home/frans/Documents/Personal/Krita/Project/MapCrunch/swiss1.kra but it is 48Meg.

Could you please also check with the final release? See https://krita.org/en/item/krita-4-3-0-released/ -- there is no assert on line 239 in the code for that build...
Retested with the final release and the assert does not occur. However it now also does not occur with krita-4.3.0-beta2 anymore. So I am afraid it is a Heisenbug.
