Keep the symptom specific

2K's support page has separate platform-specific performance, controller, network and installation advice. Match the error text before trying another category; removing every mod and reinstalling everything at once makes it harder to identify the trigger.

Observed caseScoped first checkLimit
Exact Steamworks Integration error; mods activeRecord mod list and check for outdated files; test without mods using a safe profileA clean launch does not identify which mod alone caused it

Change one variable and document the result

2K's support article was updated July 2026, but the exact UI and compatibility can still move. Use the current article and avoid deleting save or mod data without a separate backup.

  1. Copy the exact message and record OS, storefront, build, DLC, mod manager and VPN status.
  2. If modded, note the enabled list and update date; back up any mod profile before temporarily launching a clean configuration.
  3. If a VPN is active, follow your network provider's rules and test a permitted direct connection only as a comparison.
  4. Change one variable, restart the client and record whether the same error returns.
  5. If unchanged, restore the prior setting before trying the next official support step.
  6. Report the reproducible case to 2K with platform/build and steps; do not publish logs containing personal paths or tokens.

Frequently asked questions

Does a VPN always cause this error?

No. 2K describes outdated mods or VPN use as likely culprits, not guaranteed causes.

Should I uninstall all DLC and the game first?

2K's troubleshooting article separates steps; begin with the exact symptom and protect saves before broader reinstall work.

Can this worksheet detect a bad mod?

No. It records your observations locally and cannot read game files or a mod manager.
