Modern HCW (Hybrid Agent): troubleshooting like a pro

Does anyone know if Windows Server 2022 is UNsupported by Modern Agent?  I'm struggling with two separate environments (client prod, and my mimicking lab) where the Exchange on-prem servers are Exchange 2019 on Windows Server 2022.  The HCW does not reveal the Modern / Classic selection, starts at the Minimal (Recommended) vs Full page, after that goes straight to the Hybrid Domains page.

The log doesn't mention any reason, though I can confirm - no migration endpoints/batches, and this is acknowledged in the HCW log:

2023.11.03 09:42:39.476 10361 [Client=UX, Thread=1] 
===========================================================================================================================================================================================================
Public Endpoint
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
HasMigrationEndpoint | False 
MigrationEndpoints | 
NameForMigrationEndpoint | Hybrid Migration Endpoint - EWS (Default Web Site)

I only mention that because I did see this answers.ms page where pre-existing endpoints was the issue: https://answers.microsoft.com/en-us/msoffice/forum/all/exchange-hybrid-wizard-modern-hybrid-option-not/6f1b665d-27da-4d29-820e-d83b8fc91ebd

I did spot that the requirements for the Modern Agent don't list Windows 2022.  https://learn.microsoft.com/en-us/exchange/hybrid-deployment/hybrid-agent#system-requirements

The Hybrid Agent has multiple methods of installation with different requirements. In all cases, the core computer requirements are the same as described in the following list:

• Windows Server 2012 R2, Windows Server 2016, or Windows Server 2019

 I can install the agent manually without error, and after this, the HCW shows now difference, just no sign of Modern options...  Any ideas?
