QB 2022 DB service breaks others and causing multi-user mode to stop working on all previous versions.

It seems Quickbooks 2022 is 64 bit and installs to C:\Program Files folder where all previous versions are 32 bit and install to the C:\Program Files (x86) folder.

-- So if you are having issues with Multi-User Mode for Quickbooks Desktop 2022 and get the H202 error you have to use the 64bit "QuickBooks Database Server Manager" to run a scan to fix Windows firewall issues:

"C:\Program Files\CommonFiles\Intuit\QuickBooks\QBServerUtilityMgr.exe"

-- With earlier versions of Quickbooks that are installed on the same server you use the 32bit  "QuickBooks Database Server Manager":

"C\Program Files (x86)\Common Files\Intuit\QuickBooks\QBServerUtilityMgr.exe"

*** To know you have the proper version of QBServerUtilityMgr.exe running for Quickbooks 2022 go to the "Port Monitor" tab and you will see all your versions of Quickbooks that you have installed as well as the ports they are using.  If Quickbooks Database Manager 2022 is not listed there then you are using the older 32 bit version for all previous versions of Quickbooks from 2021 down.

I hope this helps,
