A number of Call of Duty: Modern Warfare 4 players on Steam report a troubling issue where, after playing several matches, the game suddenly refuses to launch. Affected users find themselves logged out of Steam and, upon restarting, see the game client demanding a reinstall. However, clicking install fails to initiate any download or update. Notably, other titles like Warzone continue to install and run normally on the same systems. This glitch disrupts gameplay and suggests a client-side or account-related bug that may require developer intervention to resolve.
- Issue occurs after initial gameplay sessions.
- Reinstall prompt appears but does not function.
