Similar to this https://docs.microsoft.com/en-us/answers/questions/378888/win32-apps-don39t-install-on-intune-kiosk....
That was posted in May, with no recent updates, other than some BS from a "Community Expert" which doesn't even come close to answering the question.
Our Win10 multi-app kiosk policy with local user logon doesn't seem to install Win32 apps after it completes autopilot. If you make the apps required in the ESP, they install fine...once... but they'll never update or get other non-ESP required app deployments, because the user is a local user and not an AAD user.
Is that the expected behavior and why is Microsoft always doing something silly like this? Basically it makes the device unmanaged. Because apps never have security vulns and they never need to be updated, right? Maybe if the Intune dev team were handed a monthly report from InfoSec showing all the app vulns that need updates to fix... just divorced from reality, I guess.
I swear I need to retire from IT.
