Nono,
Instead of burning it with BalenaEtcher (which seems to cause multiple issues lately) burn it with the program Raspberry Pi Imager.(or use win32diskimager, see link below)
No-one is blaming you, however a power outage will kill almost every SD. So if you have everything up and running again, create a backup of the SD (win32diskimager). So you can restore a fully configured image.
