Can't upgrade Rocket.Chat from deprecating to the latest version

Description:

After upgrading RC 6.2.9 to latest version via docker-compose, server load stops on ServiceBroker message and server remains unavailable for an infinite time (doesn't start listen port 3000).
The problem is that my version will deprecate on November 20 and seems that I can't do anything to solve that.

Steps to reproduce:

1. Have RC 6.2.9 version deployed
2. Run upgrade sequence:

docker-compose down
docker-compose pull
docker-compose build
# running "up" w/o -d option to see one-stream log
docker-compose up

Expected behavior:

Server started label:

+---------------------------------------------------+
|                   SERVER RUNNING                  |
+---------------------------------------------------+
|                                                   |
|  Rocket.Chat Version: 6.4.4                       |
|       NodeJS Version: 14.21.3 - x64               |
|      MongoDB Version: 5.0.21                      |
|       MongoDB Engine: wiredTiger                  |
|             Platform: linux                       |
|         Process Port: 3000                        |
|             Site URL: https://chat.domain.tld     |
|     ReplicaSet OpLog: Enabled                     |
|          Commit Hash: 5c9c3f7864                  |
|        Commit Branch: HEAD                        |
|                                                   |
+---------------------------------------------------+

Actual behavior:

Server load hangs and last message in logs is:

[2023-10-27T23:47:28.130Z] INFO  a0af315c-9eda-43eb-b2e5-0752b9fcbc45/BROKER: ✔ ServiceBroker with 2 service(s) started successfully in 601ms.

And nothing happens for a very long time.
MongoDB continue logging messages (remains working).

Relevant logs:

docker-compose.log

Start by reviewing the linked docker-compose.log and reproduce the upgrade from RC 6.2.9 using the listed docker-compose commands. Trace the startup point after the ServiceBroker message; done means the upgraded server reaches the SERVER RUNNING state and listens on port 3000.
