"Error: System service failed" after power failure

After a sudden power failure last night, my umbrel does not start anymore and states the above message in the browser. The start script says the following – is anyone able to help, please?

Failed to start containers

After flashing another mSD with a clean umbrel, the error persists (though now it says " Error: Failed to start containers").

Handy guide here might help. Let me know how it goes!
