Hello there, @LeFtyy1
First of all, welcome to TruckersMP Forums.
I'm sorry about to hear you're havin' fatal error issues, it's really common within error messages. I will do my best to help you with.
Here, I will post some possible solution for your issue:
Solution 1:
Have you tried to verify your game?
> Go to Steam Library
> Right click Euro Truck Simulator 2
> Properties
> Local Files
> Verify Integrity of Game Files
Wait until the game files are verified and try whether the error still occurs.
Solution 2:
1. Right click ETS 2 in steam
2. Select 'Launch with OpenGL'
3. Let the game run and try going into game.
4. Exit the game and go back to steam, right click ETS 2 again but this time select 'Launch with DirectX (64-Bit)
5. Again go into game and then exit.
6. Start TruckersMP up and see if the game stops crashing
After installing process, please click on TruckersMP Launcher icon on your desktop and launch it as administrator (right click - run as administrator)
And please have a look at this guides, that may help you aswell
Hope it'll help.
