Question: Missing APFS partition

After trying to create hybrid MBR for dual-booting Windows in UEFI and BIOS with gdisk, main APFS partition (container) disappeared, leaving empty space in GPT partition table. It's only possible to see with sudo gpt -r show /dev/disk1 (space from 409640 to 732027536).

Disk utility and gdisk don't show this empty space at all. It's also impossible to repair partition structure with Disk Utility. How to recover missing APFS container?
