Maybe a drive died or LVM (volume group proxvg) got corrupted due to the unexpected power loss. Consumer SSDs are more vulnerable to corruption on power loss than old HDDs. Maybe reinstalling the latest Proxmox and restoring VMs and containers from backup is the best way (as you might have silent data corruption)?
