HA doesn't boot up on my Raspberry PI 3B

Hi there,
I don’t know what happened. I perfomed a system update on my current Raspberry PI 3 Model B which caused the system to not boot up anymore (I can ping but I cannot access).
I’m trying to get another HA on a similar Rasbperry. I flashed a SD Card and inserted it using the regular procedure but the system doesn’t start as if the image was not a bootable one.
I have tried with Balena Etcher and with Raspberry PI Imager. None of those look to make a bootable system. Would anyone have a clue or got the same issue ?
Thanks
