The “0xc0000005” is a particularly horrible one. It’s an access violation error.
Essentially “FlightSimulator.exe” has accessed something that it shouldn’t, and crashed.
The only advice I could give is strip away anything that didn’t come with the sim, no community addons at all, and fly default aircraft. When you have established a base line of stability, and one flight without a crash doesn’t count here. You might need to fly for several days with the sim trimmed back like that.
Only then start to add addons back one at a time. Also, whichever addons you are using, make sure they are the latest version available. Don’t use an addon written for sim as it was a year ago, for example.
