Exchange 2019 CU14 Installation keeps Failing at Mailbox role: client access service

Question

Hello,

I'm fairly new to dealing with servers and the world of IT, so please excuse my ignorance if this turns out to be a simple error, although I have done my research.

Exchange server keeps failing at mailbox role:client access service, error photo attached below. Event ID is 4027 and source is MSExchange ADAccess.

I'm currently working on VMware Workstation with the exchange server set up on a different machine than my Domain controller, and I'm setting up exchange server on a separate user (not Administrator because I kept getting a lot of errors about forest level, and it's not detecting domain) that is part of the domain and member of (Enterprise, Schema and Domain Admins). I've also made sure forest level and domain are 2016. Also made sure to prepare the AD beforehand and passed prerequisites check. Firewall is off, remote desktop is on, and I downloaded the latest exchange server update

As a last resort I used Setup assist, it keeps failing at finding mailbox role, and I'm not sure where to go from there. Only other case I saw similar to this was solved by uninstalling via command line.
