Moving to a new residence and gaurentee company retraced approval notice days later. What to do?

I applied for a new apartment and had a gaurentee company approve me. They sent the approval to the management company and they drafted all of the official documents to sign and where to send the money. I canceled my current place and started transferring funds.

A few days later the company retracted the approval. My realtor and the management company said they’ve never seen this before. Is there anything I can do about this? Or am I just effectively homeless and have to restart the apartment process?
