Hey @hermsats if you’re still having this issue you can follow the steps under “Resolving Corrupted Blockchain Issues” in the Official FAQ here: Official Umbrel Troubleshooting Guide and FAQ

If the issue persists please post the full debug log, as a note too when following the steps there avoid rebooting after adding the reindex=1 line or else it will attempt to reindex after each reboot
