Finally… after countles of hours testing my hardware, different windows versions and also a YAARRR version of mfs2020.
This post https://forums.flightsimulator.com/t/ctds-temporary-fix-awaiting-patch/265544?u=mahognyz
fixed it for me.
I use the Microsoft Store version of mfs2020 and all up to date version of MFS2020
In my pursuit for ruling out sources of error, I in desparation tried the yaarrr version of mfs2020 to test if there was any difference in stability.
Normally I would have multiple CTD´s during install, in menu and in flight.
Yaarrr version worked flawless, no ctd´s anymore. I could fly for 15-25 hours and this went on for days while testing.
Yarrr version does not uses internet so NO bing maps/Online features BUT the sole purpose was also to rule out hardware related CTD´s.
So I could conclude that :
My hardware was not the culprit og my CTD´s
Yaarrr version is based on steam, could this be an issue with ms store
version?
Yaarrr version runs offline so could this be internet related ?
So I went back to testing the MS store version with offline play but CTD´s where back.
So i tested like 4 different windows 10 vanilla installs and 4 versions of windows 11 but still CTD´s
Until I saw the fix with killing ■■■■■■■ explorer.exe in taskbar.
I know that CTD´s can have root in so many different scenarios but for me this was all related to this single process running.
It is a versy easy fix so try it and send some love to Zixxstar for finding this.
