Source2MainInternal(): Bootstrap::Init returned false

I was working on a gamemode but i think an update broke a feature, so i downloaded an older version of s&box through the steam api on python and i got this error upon launching the game. The manifest id i used to download s&box : 5147961037839237626.
any ideas on how to fix this ?

If you have recovered a crashdump file, try opening an issue here or on Discord.

Try deleting and using a fresh install whilst re-validating the steam files. For the game, If you end up fixing it don’t forget to reply with an update incase anyone else gets this problem. Goodluck :frowning:
