Game crashing loading into my local server

Not so much a oxide issue directly but I have set up a local server correctly but whenever I try to load into it my game begins to lag terribly and then crashes to desktop, usually towards the end of asset warmup
When running the script to create the map I did have errors in relation to missing some helicopter and boat meshes for some reason, aswell as missing shaders. I am not entirely sure on what exactly the message was

CPU: i9 9900k
GPU: RTX 2070
RAM: 16gb 3200mhz

I've checked the task manager and the server uses around 4gb of RAM leaving me 12gb for the game ao I can't see that being the issue. As I've said I have no issue what so ever playing the game normally so I do not know what I am doing wrong.

Can somebody assist?

how are you joining your server ? try hitting F1 and drop this into the console.

client. connect localhost:28015

you also never said what was crashing the client or the server ? its never a good idea to try and run play both from the same box tbh

That's exactly how I'm joining it and it's the game itself that is crashing, the server is still operational afterwards. I'm only wanting it for myself, nobody else will be joining 

If you can play the game on any other server fine then delete your server and re set it up it may have corrupted during initial setup. Or less likely is your system isn't up to the job of running both. There isn't a lot of other options it could be
