If the error only happens when you open one specific drawing but not others, the file is likely corrupt. Specifically, Error 2602 has been linked to Visual Styles in 3D modeling. If a drawing tries to render a "Realistic" or "Conceptual" visual style using a buggy driver, it will crash instantly.
How to fix it:
Error Message: Internal Error 2602 Software: Autodesk AutoCAD (and verticals like Civil 3D, MEP, Architecture) Severity: Critical (Application Crash)
