CTD with A350 on Long-Haul Flights Only (FS2020) – Need Help

Hello everyone,

I hope you're doing well.

I'm experiencing a recurring issue when flying the A350 in Microsoft Flight Simulator 2020. On every long-haul flight, the simulator eventually crashes after a few hours of flight time. Unfortunately, I only managed to capture one screenshot of the error so far (I’ll make sure to document future crashes better).

Key details:

• This issue only occurs with the A350, and specifically on long-haul flights.

• Short-haul flights with the same aircraft work perfectly fine—no crashes at all.

• The crash seems to happen mid-cruise after several hours of stable flight.

My Setup:

• Ryzen 7 5800x3d
• RTX 5070TI (with last driver updated)
• 32GB DDR4 3600mhz

My Game Addons:

• Microsoft Flight Simulator 2020 (DX12 + TAA + FG ON)

• REX Atmosphere

• Active Sky

• A350 Inibuilds

Examples of affected flights:

• KSAN (LatinVFR) → EDDM (Sim-Wings)

• LIMC (Aerosoft) → KBOS (FlyTampa)

• KMIA (LatinVFR) → SCEL (LatinVFR)

If anyone has experienced something similar or has any suggestions for troubleshooting or potential fixes, I’d greatly appreciate your input. Thank you in advance!
