• S/4HANA Cloud
• SAPUI5

• You are trying to adapt the UI in P-system.
• The changes as key user are supposed to be done in the Q-system and moved to the P-system with the export/import collection functionality.

• Changes should be done in the Q-system and added to a collection for export to the P-system.
• Refer to the following documentation on how to adapt the UI as Key User:
  
  • Adapting SAP Fiori UIs at Runtime - Key User Adaptation
• For more specifics on publishing the changes see the following documentation:
  
  • Publishing UI Changes
• Note that in SAPUI5 1.92 and later this exception should be caught and a more user-friendly error displayed instead
