Hello ServiceNow Community,
I hope you’re all doing well! I’m currently working in my Personal Developer Instance (PDI) and encountering an issue with the UI Builder. When I try to open it, I’m seeing the following error:
*“Could not serve invalid request for UX Page Registry, sys_id: 13df404077733300cf3a2a691061bc”*
Has anyone else experienced this or have any insights on what might be causing it? I’d really appreciate any suggestions or troubleshooting steps you could share to help me resolve this. Thank you so much in advance for your time and assistance!
Best regards,

I had the same issue. I updated and repaired UI Builder and still had the issue.
I tried from All --> UI Builder the same way @StefanMunich24 did and it works from there. Thanks for the tip!
