Invalid requesting-user-name value after system reboot (IPP Everywhere)

When I add a IPP Printer, it works fine until I restart OS, after system reboot the requesting-user-name contains WORKGROUP\VM132786998$ so it's domain\computerName$. And the user cannot be correctly recognized.

 

Steps to reproduce it:
1. Add IPP printer
2. Print Test page
3. Restart system
4. Print Test page

 

Current result if inspecting by Wireshark:
at point 2. requesting-user-name contains correct "Administrator" value
at point 4. requesting-user-name contains incorrect "workgroup\VM132786998$

 

Expected result: in both cases correct value Administrator must be present.

Currently only restart print spooler or recreating printer solves the issue. (See attached wireshark captures before and after print spooler restart)

 

Note: The issue is not reproducible in build 22H2 22621.3447. I'm able to reproduce it in 23H2 22635.4076.

 

Same error is observed here (comment from Douglas Kosovic): https://learn.microsoft.com/en-us/answers/questions/1428508/ipp-everywhere-ipp-2-0-server-basic-authentication

Attached screenshots from wireshark captures when it's happening and after restarting Print Spooler.
