If nothing I suggested worked there’s really nothing that could be wrong. Reinstalling the addons and such, especially with a fresh install of Garry’s mod should fix anything and everything.
- Are you using any betas?
- Are you updated to the latest version?
- Have you tried other vehicles in-game
- Other servers with VCMOD?
Try deleting all of your addons and starting Garry’s mod again.
Upon restart (after deleting all addons from: steam apps/Garry’sMod/garrysmod/addons folder) it will reinstall addons onto your game and you should be able to rejoin the server. Even if you don’t have all addons, ensure that your multiplayer settings (gmod main menu- options- multiplayer) accept all custom files from the server you’re joining.
If that does not work, unsubscribe from all workshop addons, delete the game itself (and all files inside of it) and reinstall as if you just got the game.
After, subscribe to the content pack again, load in, see if that works.
- memorize vital settings
-anything else personalized to your liking.
The only thing chromium does is let you watch the TVs and listen to the radios in-game. Other than that, you might as well turn it off if you’re still having problems, if it doesn’t change anything by all means turn it back on.
