If you haven't touched or made changes to any of those system files in HLDS and getting this error, make sure;
- you have a folder named "steam" outside of server folder. for an example if you are running the server from this directory: /root/cs/ there should be a steam folder located here: /root/steam
- you haven't touched any content in that steam folder, this steam folder gets automatically created when your running SteamCMD to download server files, and it's directory is detected according to the directory you have originally ran SteamCMD in the first instance, not sure if there is a way to force it's directory.
- recheck your HLDS launch parameters again and make sure if all files required for your server is there, like map files, models and sprites, it should be all intact if you haven't touched it. But usually those errors will show up in the server console.

If this does not still resolve, you might need to re-download server files using SteamCMD. Good luck with that because that download is bugged damn much, you might need to execute the same command so many times, yet not get all server files downloaded.
