Error at Starting the game
I just started the game today with this Issue below. I don't know what the error means and why it happens. Yesterday it works everything fine and i didn't change something. The tool from steam for fixing files didn't help

How can i fix that?

Delete the CO folder in user/AppData.
Backup save files first. Folder will rebuild at next start. Replace save folder to same spot.

It's always AppData if Verify and Skyve failed.

Idk what happened. My game crashes when loading a save game and I didn't changed nothing. Also it comes back with all default settings of the game on launch. Graphics, Music...everything default every time I launch! This game sucks :(

Verify CS2 game files on Steam. Use Skyve to fix mod conflicts. Both must be done. These posts are so boring. Do the work.

yeah good luck with that advice, why is it people that ask for help from some failed mod and then never take the advice? NVM looks like he did finally take your advice.

it would be nice if people who are using mods could think rationally and understand after a game update the mods need to be updated too

Honestly, i have the same issue, its clear it is a mod.
However, because of the error messages, it does'nt let you enter the menu even.

You either have to option to continue, wich keeps giving errors, or quit game

So you can not even turn of the mod in question that is giving the error.

Sometimes this problem is caused by the way pdxmods is cached and managed. Sometimes removing or disabling mods (whether its from skyve or from pdxmods directly, game or browser) doesn't clean out the mod completely, and there is stale data in there that can get picked up and causes instability.

Hopefully if mods ever get out of "beta", they've figured this stuff out. Because of this people misunderstand the issue and think mods themselves are the problem when its often the integration of mods with the game that is problematic (and something CO/PDX are responsible for).

Also, this was never an issue that I ever saw occur in CS1, and I played a HEAVILY modded game.

Awesome! sorry for my rude reply.

If you mark it as solution others may see it before posting same old thing.

and like major kudos has been repeatedly telling people on here, there are very easy ways to get around that to remove and disable your mods without having to launch the game period

Everything fine, thanks :) Not everyone has a well knowledge about staff like this and needs helps, sadly in forums there are a lot of trolls and people without brains. I am really happy and grateful that there are people like you who help others.

I hope a moderator is looking at this thread because it could help a lot of people, who doesn't familiar with stuff like this.

And again: Thanks you for your help!

It is a hidden folder. You need to "show hidden folders and files" in windows to see it.
Google "show hidden files windows 11", that is the easiest way to learn how.
