Hi again
Had another more detailed look at your XP11 Log.txt file and as far as hardware is concerned, all appears to be OK in terms of CPU, GPU, RAM, OS etc.
In terms of what XP11 was doing when it stopped recording data in the Log.txt file, this was the last entry:-
Fetching plugins for C:\Program Files (x86)/Steam/steamapps/common/X-Plane 11/Aircraft/Laminar Research/KingAir C90B/plugins
Loaded: C:\Program Files (x86)/Steam/steamapps/common/X-Plane 11/Aircraft/Laminar Research/KingAir C90B/plugins/xlua/64/win.xpl (com.x-plane.xlua.1.0.0r1).
Just as an exercise, I loaded the same aircraft into my copy of XP11 and I get the same data entry, but in my case, I also get the following initial entries shown below, to an eventual and successful launch of XP11 itself.
In your case, these data entries are not being made and XP11 simply shuts down?
0:00:15.166 I/SND: This aircraft is using FMOD in FULL mode.

Suggestions:-
1. Open the XP11 Installer app and rerun it, as this should check to make sure that you have no missing or corrupt files
2. Load another default aircraft into XP11 and advise if it loads OK?
3. As a precaution, always check to make sure that you have installed the very latest NVIDIA drivers for your GeForce RTX 2060 graphics card?
4. I note that you have installed the MisterX6 Airport Environment HD addon into your custom scenery folder. Please copy and paste this out of the custom scenery folder to somewhere safe and try loading XP11 again.
Can't think of anything else currently, but hope this helps as a start :-)
