What the error means

Your antivirus may have isolated the correct DLL. You need to restore it and prevent it from happening again.

The error specifically mentions an "entry point" related to Steam’s internal interface. This usually points to a corrupted steam_api.dll file inside the game's folder.

Sometimes, the application you're trying to run depends on a specific version of a library (in this case, likely related to Steam) that it can't find.

In Windows programming, a "procedure" is simply a function or a set of instructions. A "procedure entry point" is the specific memory address where that function begins. When an application (your game) runs, it tells Windows, “Go to this entry point and execute the code there.”
