Game keeps crashing!

Hello everyone,

My name is AppleSnipe and my friend has played rust for a long time but since 6 months ago his rust keeps crashing giving the error stated down below if anyone could help that would be great because he doesn’t play rust anymore since this error keeps appearing

side note: (the game crashes after loading in an server he could walk around for a bit but as soon as he types [enter] his game crashes giving the error below, or his game crashes after 2 seconds of walking without using chat).

Error:
