Cant join any server

keep just getting >System.NullReferenceException: Object reference not set to an instance of an object whys this happening

I’ve uninstalled rust
Switched it from betas
I dont know what to do now

Try validating your files in Steam

I’m pretty sure the error you are getting is referring to an item that is in your inventory has the wrong ID or the item you have in your inventory has no ID. This is all server side which would result in a null function and has nothing to do with Rust client. This would auto kick you from the server you are trying to connect to if the item is still there. The only way I have fixed this was to load inventory guardian on my server and wipe my own inventory. http://oxidemod.org/plugins/inventory-guardian.773/

Edit:
you could also have a friend that you can trust and go in your base and kill you as this might work also, but i haven’t tested this.
