This afternoon I updated my version of ESPHome Builder from 2025.3.0 to 2025.3.1 and on attempting to update my 11 ESPHome SmartPlugs, every single one of them failed the update with the following output:

Obviously I don’t want to have to start cracking open the plugs to flash them physically, so does anyone know or have any ideas how to resolve this?
