Quick answer: Verify Arma Reforger’s files in Steam, install the current game update, and test a vanilla session without Workshop content. If the crash remains, send the built-in crash report with exact reproduction steps.
Source note: The source video had no usable transcript after the required retries. Its visible title, description, and chapter cues were used only to identify the problem; the repair steps below were checked against current first-party support on September 29, 2026.
Before you start
- Write down when the crash occurs: launch, server join, loading a scenario, or during play.
- Note whether the server or scenario uses mods.
- Let Steam finish all downloads before testing.
Fix Arma Reforger crashing on Steam
- Restart and update. Exit the game and Steam, restart Windows, reopen Steam, and allow every Arma Reforger update to finish.
- Verify game files. In Steam Library, right-click Arma Reforger > Properties > Installed Files > Verify integrity of game files.
- Test without Workshop content. Temporarily disable or unsubscribe from recently added Reforger mods and join an unmodded official scenario. Re-enable items one at a time after a successful test.
- Remove custom launch options. In Properties > General, clear launch options you added yourself, then retest. Do not add undocumented flags.
- Update the graphics driver and Windows. Use the GPU manufacturer’s official app or site, install current Windows updates, and reboot.
- Submit the crash report. When Bohemia’s Crash Reporter opens, include the exact action, server/scenario, active mods, and whether the failure repeats. Keep the report GUID.
- Attach logs when escalating. Reforger game logs are stored in
%userprofile%\Documents\My Games\ArmaReforger\logs. Send the relevant timestamped files through Bohemia’s Feedback Tracker.
Why this works
File verification repairs a damaged or incomplete Steam installation. A clean, unmodded test separates a base-game crash from a Workshop dependency or version mismatch. Accurate crash reports and logs give Bohemia the game version, context, and technical data needed to identify an engine or content bug.
Alternatives
- Try a different official server or scenario to determine whether the crash is server-specific.
- Close nonessential overlays and monitoring tools for one test, then restore them.
- If a new update introduced the crash, check the current Reforger changelog and known-issue notes before reinstalling.
Warnings
Do not download replacement DLL files, delete the entire Documents folder, or disable the crash reporter. Back up any local configuration before removing it. Mod testing is reversible: keep a list so you can restore the working set.
FAQ
Will verification remove mods?
Steam verification checks the base installation. Workshop items are managed separately, which is why a vanilla test is still useful.
Where are Reforger crash logs?
For the Windows game, Bohemia documents them under %userprofile%\Documents\My Games\ArmaReforger\logs.
Should I reinstall immediately?
No. Verification is faster and less disruptive. Reinstall only after the smaller tests fail and your connection can restore the game.
