Can't configure AAD Sync

I just updated the AAD Connect tool to the latest version and no longer could run the sync service. I tried uninstalling and reinstalling the app to hopefully clear out anything from the old version. Each time I try to configure I get the following failure screen.

AAD Connect installation fails with AAD Connect Failure

I tried resetting the Sync service account user in our cloud tenant to force the installer to create a new one, but it still gave the same result. Do I need to delete the Sync service account user in Azure cloud?

I have included the trace file

    I found that Windows Server 2022 Standard does not have TLS 1.2 enabled by default. I followed this to enable TLS 1.2 https://learn.microsoft.com/en-us/entra/identity/hybrid/connect/reference-connect-tls-enforcement#powershell-script-to-enable-tls-12 and then installed the latest Microsoft Entra Connect.
