Fix: Exit Code 1 (Prominence II crash)
“Exit Code 1” is a generic launcher message that usually means the game crashed during startup. The fastest way to fix it is to remove variables (shaders, extra mods), confirm memory settings, and re-install from the official modpack page.
Fast checklist (5–10 min)
- Restart your launcher (CurseForge/Prism/etc.) and try again.
- Make sure you installed from the official listing: Prominence II: Hasturian Era on CurseForge.
- Temporarily disable shaders and resource packs (they can crash on load).
- Remove any extra mods you added on top of the pack (test with a clean profile).
- Allocate 8–10 GB of RAM (then test). If you already set very high RAM (like 16–24 GB), try lowering it.
- Update your GPU drivers and reboot.
Common causes
- Shader pipeline issues (Iris/shaderpacks) — try launching without shaders first.
- Not enough memory allocated (or too much, causing long GC pauses).
- Corrupted config files after an update.
- Mixing loader types (don’t add Forge-only mods to a Fabric pack).
Get help faster (logs)
If it still crashes, the next step is checking logs. Look in your instance folder for logs/latest.log and crash-reports/. If you share logs publicly, remove any personal info.
Join a server (test)
Once the game launches, you can confirm everything works by joining a server:
