Hello Rodrigo Amorim
Since the Activity Log does not show a delete event, it's essential to consider other logging options. Ensure that logging is enabled for your storage account going forward, as it won't help recover the lost blobs but will provide data for future incidents. You can explore Azure Monitor for logging details.
You can use the Azure portal to view and restore soft-deleted blobs and snapshots. Restoring soft-deleted objects is slightly different depending on whether blob versioning is also enabled for your storage account. For more information, see Restoring a soft-deleted version.
Refer this Articles:

If you have backups configured for your storage account, consider restoring from those backups. If you haven't yet enabled backups, you can have a look into enabling that to prevent future issues.
NOTE: If soft delete, versioning, or point-in-time restore were not enabled, there is no native way to restore the container or blobs.
I hope this has been helpful!
