Thank you BIGNEWY, thanks for letting me know how to help the troubleshooting, the log now has been uploaded.
And the main trouble Me and My friend experienced is the F10 MAP, once we open the F10 MAP, our RAM use rate boosted a lot, my friend's PC can't hold that, got CTD. On my end, the mission became very laggy, after I switch back to F1 Pilotseat from the F10. There were a lot of white flagged tire shown in the map, we're not sure if that cause the trouble. Thank you once again, and do please let me know if there is some other kinds of assist is needed. I love DCS.
