Hi ,  
I’ve noticed that when the **UI Inspector** is enabled in the **Pega Infinity 25 Constellation application** , components do not load or function correctly. This issue affects both **OOTB controls** (for example, the Date control calendar Pop-out is not working) and **custom components** we’ve built for business requirements.

Is there a known reason for this behavior? Could it be a limitation of the UI Inspector or a potential bug? Has anyone else experienced similar issues, and are there any recommended workarounds?

Looking forward to your thoughts and suggestions.

@RohitGaneshHi, thanks for raising. Inspector is in beta so use with cautions. Observed behaviour sounds like bug please create ticket. What I have seen in calendar component breaking when inspector is on.
