Why does this happen when I load into this particular map

Every time I load this map made by beamng, it just results in a baseplate area, I've uninstalled and redownloaded the game and it still appears, pls help, in the image, there is a floor which is blue, for some reason the photo is extremely bright. The map is West Coast USA

 

Try launching the game in safe mode: Launcher -> Support tools -> Launch (safe mode)

 

i just tried it and the map completed loading which means its a problem with my mods i think, also could have to do anything with saving the map with changes? I think i saved something after exiting the map and it hasn't loaded after that.

 

You can try moving your userfolder to another location on your PC. If you launch the game it will create a new userfolder, and then you can add back anything you want to keep, like mods, configs, settings, etc. Just make sure to check the game after moving something as it could cause the bug to come back.

 

Bad Jbeam for pickup. If a Jbeam has typo it will make your truck usually white and it will fly through the air. Not sure if that is what it is doing here. But happens to me all the time.
Everyone else is right to tell you to rename the user folder to 0.34old and let game make new one. It is what safe mode is doing. Then you can put your mods in one by one to find the one having the problem. If it is a custom map, then press the ~ key and look for red errors. Also do this when that truck spawns. Copy and paste the into chatgtp and it can explain
if far better than most of us. Well, let me say me for sure.

 

Check console and check for errors or send an screenshot if you can't understand anything there
