Past employer’s funds listed as “Terminated Maintenance” in Fidelity. Is the money gone forever?

I recently logged into my Fidelity account and noticed that my balance had dropped by nearly $3k. When I checked my activity, I saw that two transactions had occurred under the account of a past employer. The description of the first was listed as “withdrawals” with a balance of nearly $3k being withdrawn; the other transaction was listed as “Terminated Maintenance.”
This is a past employer, but I’d recently been in contact with them after I was unable to roll over funds because I was still listed as an employee under them. If it’s helpful, I was last employed by them in June of 2022.
My question is whether I’ll be able to recover this money. Did this happen because it’s been so long since I was employed?
