There is no confirmed, error-specific fix for Dev Error 615 in Call of Duty: Modern Warfare II. A 2023 guide and player reports associate it with trying to climb or hang from a ledge, but they do not establish one cause or prove that any troubleshooting step will resolve it. Start by checking for updates; on PC, update your operating system and graphics drivers, then verify the game files. If it continues, report the issue to Activision.

The available guidance is from 2023 or earlier. An official-site search for this exact error and game returned no results, so it is not possible to confirm whether a later update fixed it or whether it remains an active issue.
Try these troubleshooting steps
- Check for a game update. Use your platform’s launcher or console update interface and install any available update. Dot Esports recommends ensuring the game is fully updated.
- On PC, check operating-system and graphics-driver updates. Install available updates using the relevant system or graphics-card tools. This is general troubleshooting guidance, not a confirmed error-specific fix.
- Verify the game files on PC. Use your launcher’s file-repair option to check for damaged or missing installation files. The cited guide specifically mentions Battle.net’s Scan and Repair; the exact menu differs by launcher.
- Contact Activision if the error persists. Report the platform you play on, what you were doing when the error appeared, and which steps you have tried. These details can help describe the problem; they are practical suggestions, not a published error-specific support requirement.
What to expect from these steps
The cited guide offers updates, PC maintenance, and file verification as general measures. It does not report controlled testing or demonstrate that they fix Dev Error 615. If the issue comes from a game-side defect, a developer patch may be needed; the current patch status is not established.
