| Issue | Likely Cause | Solution | | :--- | :--- | :--- | | Game crashes on startup | An SKSE DLL plugin is for the wrong game version. | Verify you have the correct 1.6.640 version of all SKSE mods. Check mod pages for updates. | | "You are using a newer version of Skyrim than this SKSE supports" | Your SKSE version does not match your game version. | Download from skse.silverlock.org and install it properly. | | Some mods not appearing in-game | Incorrect mod load order or missing master files. | Use LOOT (Load Order Optimization Tool) to sort your load order and check for missing dependencies in your mod manager. | | Infinite loading screen | Corrupted save or script-heavy mod conflict. | Try loading an earlier save. Disable recently added mods one by one to isolate the cause. Use tools like FallRimTools or ReSaver to clean your save file. | | New update available on Steam | Steam is trying to update your game. | Re-apply your "Only update on launch" setting. Consider setting your appmanifest_489830.acf file to "read-only" as an advanced precaution. |
