Finally, i am also stuck with the most common error "Unable to load groups " when starting the Launchpad in 7.4 system with a central hub deployment running SAP_UI5 - SP10 and system details as below
In the process to fix this , we have applied all the required notes in the front end system as suggested here and followed the steps described here . As a result the UI5 runtime libraries should upgrade to 1.24.3 or higher, but only a few were only upgraded to 1.24.3 and rest in 1.24.2 and 1.24.1 .(SAP.FIORI , SAP.UISHELL ,SAP.Ushell_abap were in 1.24.3)

Adding to that the launchpad designer also has an error loading the catalogs in chrome ,(Catalogs are loaded successfully in IE , screenshot attached)
Error: "Unable to load groups"

Any pointers to fix these ?
