If you had read your log.txt (yes, not only devs can do this, even the mere mortal user can) - you would have found this:
E/GFX/VK: Vulkan device lost error!
0:00:06.446 E/GFX: No diagnostics for graphics queue, queue was empty!
0:00:06.446 E/GFX: No diagnostics for transfer queue, queue was empty!
0:00:06.446 E/SYS: MACIBM_alert: Encountered Vulkan device loss error!
0:00:06.446 E/SYS: MACIBM_alert: X-Plane cannot continue running and will now quit.
So, there are two things problematic with your setup:
1.) You are running some plugins that can cause problems (new XPUIPC is not compatible, older version is), FlyWithLua (depending on the scripts)
2.) You are running the latest Beta of X-Plane and suffer a device loss error...which has nothing to do with IXEG.
