I'm just another simmer in the UK, but assuming that your PC hasn't coincidentally developed a hardware fault, then the cause of the problem is more likely to be a corrupt X-Plane file (scenery file?) or Plugin file?
I've read of other cases from simmers where they had similar problems and were asked to remove certain scenery files?
Try running the X-Plane 11.exe Installer software (not the X-Plane app itself) and click on the Update X-Plane button. Your X-Plane files will then be scanned and updated automatically if there is any problem.
I would suggest also that you save all of your plugin folder/files to a temporary folder and delete the ones in the X-Plane 11/ Resources/Plugins folder, before trying to open X-Plane again. You can always put the plugins back again afterward.
If none of this works, then I would further suggest that you formally send X-Plane a bug report through the correct website page, along with a copy of the X-Plane log file.
Hope you manage to get things sorted out :-)
