delete lxd snashot

Hello

I 'have snapshoted lxd container. I did a mistake by deleting this /var/lib/lxd/snaphots/container_snapshoted. When i ran lxc info container, it always referenced to a snapshot. But, now, it's impossible to delete this snapshot, it outputed error,not found.
So, i created a new snapshot, called with the same name, in order to populate the repository deleted. It didn't run, impossible to delete the snapshoted container too.
Do you know how can i delete this snapshot ? Maybe, it referenced or hardcoded somewhere ?

Best regards
