Any Ideas

Get this when loading the business game

There could be many reasons, can you check in-game console for more extended error?

If it's you project, you need to delete all  .idea folders from your project, publish it and it will fix the issue.

its not my project. its the buisness on on top games
others are playing on it fine it looks like

It works for me which is weird, i would try to clear games cache steamapps\common\sbox\gamecache or reinstall S&Box

Sometimes even changing game version from public to staging might help

If nothing helps, try to contact game developer in their discord that they specified in game description, if it's of course an issue only for this specific game

If you figure it out, please post info about it for people in future
