I had a similar CTD (0xC0000005) problem on long flights. The solution was to increase virtual memory, which you can find here.
Win11 → Adjust system appearance and performance → Advanced → Virtual memory (change). I set mine to a range of 5 to 90 GB to be safe for very long flights up to 8 hours, and I haven’t had a single CTD since. I have 32 GB of RAM and an RTX 5070 Ti.
