All FBA Inventory has disappeared (1000+ FBA inventory is now showing as 0 in FBA inventory on seller central)

My account health is very good, I have small regular stranded inventory (which has been same for few days now), I have checked inventory ledger report, though I am unable to find where amazon has misplaced my inventory.

My FBA inventory turned to 0 units yesterday for months it has been above 100,000+ for total inventory for all my SKUs and now it is showing out of stock.

I am losing out on sales everyday

Can anyone help?
