Roblox pushes updates every Wednesday to patch client vulnerabilities. When this happens, outdated executor versions may crash or close instantly upon launch.
Quick Fix Checklist:
1. **Check Version Compatibility:** Ensure you have the latest Arceus X build compatible with Roblox's newest version number.
2. **Clear App Cache & Data:** Go to **Settings > Apps > Arceus X > Storage > Clear Cache**.
3. **Disable Battery Optimization:** Aggressive OS task killers (common on Xiaomi, Samsung, and Huawei) can terminate the executor's overlay service. Set battery usage to 'Unrestricted'.
4. **Re-install Fresh APK:** If files got corrupted during an OTA update, delete the app, reboot your phone, and install the fresh release from our portal.
