Hi @mmerelles so I read the log.txt (posted above) after I launched it again and it seemed that my newly installed SkyMaxx Pro was the problem, so I uninstalled it, and launched X-Plane again. Still X-Plane crashed after the B737CL was loaded.
P.s I know I have a slow graphics card, but my CPU handled the plane flawlessly for the first few days. So I am kinda confused now on why it is failing.
Here is the updated log.txt:
