When I go to lunch the BeamMp launcher this is the response the launcher gives me:
[5/5/2025 13:01:25] [ERROR] Exception in main(): file_size: unknown error: “C:\Program Files (x86)\Steam\steamapps\common\BeamNG.drive\integrity.json”
Please try verifying your game files via steam and then playing singleplayer for a bit.
I will try that thank you
