I get the error with ../sap/bc/ui5_ui5/arsvc_upb_admn/main.html
If I use /ui2/flp to launch ../sap/bc/ui5_ui5/ushell/shells/abap/FioriLaunchpad.html?sap-client=010&sap-language=EN, I see the Sales and Distribution tile but when I open it, I see "Loading tiles" (as described in Note 2251801) which never resolves.
