Separately, Microsoft warns that Windows 11 version 23H2 will reach end of support on November 11, 2025. Users must upgrade to version 24H2 or 25H2 to continue receiving security updates.
Windows 11 23H2 was the last version that supported Windows Mixed Reality. They're really in a hurry to kill WMR.
Microsoft got companies like Samsung, HP and Lenovo to make WMR VR headsets that require the WMR Windows components. There is official support for Steam VR, but the headsets don't work if the WMR components aren't there, and after November there will be no officially supported version of Windows with those components. From what I've read it's basically impossible to get WMR working on 10 LTSC, and I assume the situation is the same on 11 LTSC.
