The Problem are only with add-on third part sceneries developer included orthoimagery on the same country grid ! In this case, your sim not start !
Not confuse with defaut airport included in MSFS ( And i'm not sure LOWW from Gaya included orthoimagery in this folder )
For Alesund use with ENVA from A.S., the solution are deactivated the folder Orbx-aerial-enal-alesund and waiting the patch ...
Hopefuly Asobo solve this in the next days !
