Home buying dilema

Hoping someone in here has been in a similar circumstance, but after searching this might be a first time subreddit question.

My chapter 13 bankruptcy was fully completed on 5/18, however final check was just dispersed this week. I am currently in the process of buying a home, as I was told as soon as my bankruptcy was completed we would be good to go, per my lender. I have fully rebuilt my credit using a car loan I had due to trustee approval, and a credit card.

I am literally in the underwriting phase of my home loan, have done inspections, appraisals, have earnest money put down, and everything. Just now the underwriter is asking for a trustee approval letter, and my closing date is supposed to be 6/30. Is there any chance I get that letter in time? I messaged my lawyers and called the trustee office, but of course it’s outside of business hours.

Has anyone ever been in this boat? How did it go & what do I have to look forward to. My car loan approval took 21 days from submission to approval letter received. Wondering if this will be more of the same.
