I still haven’t been able to launch the game once.
I tried most of the suggested workaround, but it still CTD before or just after reaching the main menu.
I bought the game from Steam, I’m running Windows 11 Pro, AMD Ryzen 9, 32 GB RAM and Radeon RX6800 XT, 750W power supply (required <600W). No mods yet, no overclock, no USB peripherals, no antivirus, no other applications. Just a clean install of Windows 11 and Steam.
Error code: 0x80000003.
What I tried so far:
- updated BIOS
- uninstalled and installed again from scratch, two times
- in Steam, verified the integrity of the files
- tried to run MSFS in safe mode
- applied all the pending Windows Update items
- checked dxdiag: no errors
- tried both the Adrenaline and Pro versions of the drivers
- set the virtual memory to fixed size (16 GB)
- set the virtual memory to automatic
- disabled the network before launching MSFS (often reaches the main menu but CTD a couple of seconds later)
- changed the AMD Radeon profile: Game, Power save, etc…
- disabled the Steam Cloud Save and removed its folder
The behavior is always the same.
