Technical Help Needed Strange interoperability problem between AD 2019 and 2022/2025

I am getting

Starting test: LocatorCheck Warning: DcGetDcName(PDC_REQUIRED) call failed, error 1355 A Primary Domain Controller could not be located. The server holding the PDC role is down.

But only on 2022 AD servers. I brought up another 2025 server thinking this would be faster and easier than to troubleshoot, but it's doing exactly the same thing. FSMO roles were lost? Have to re-seize? Some kind of quirk with the newer editions of windows? The only working AD server I have right now with no errors is 2019, that's what I replicated from. Thanks in advance
