Hi Momo,
yes i´m pretty sure i have tried every step listed in the Crash Checklist.
Have tried vanilla installations, different mods and then clean install, new SSD and so on.
Also i have disabled Defender, enabled and tried to manualy add the apps in the exception list as descriped.
One Drive has been disabled. enabled, suspended. It makes no difference.
With 1.5.9 i can launch the Sandbox everything works fine, Campaign still crash before faction screen.
