CEP Panels not visible

[Maor5C10]

Hey,

I've a problem with Premiere 2025 that all of my extensions is like unvisible,

I mean, I can open them, I can guess where to click (and everything works) but the GUI isn't loading.

Thank you

Specifically, in which PPro version are you testing? [The About box version, not a year]

Confirming: Your extensions seem to work, but you cannot see them?!

I wrote a caption for the photos but it didn't add it but: My extensions seem to work, I can click button based on my memory but the UI isn't loading

Was your extension installed from a signed .zxp file, or are you using PlayerDebugMode to enable the loading of unsigned extensions? 

[Maor5C10]

I tried both, ZXP signed and PDM.

Both behave the same way.

In PP 2024 it work perfectly. and it's relevant to all the extensions I have Installed on my Macbook.

Interesting! We've never had a report of behavior like that before. 

PPro 25.0 integrates CEP12, so you'd need to set PlayerDebugMode again (for CEP12 instead of CEP11), in order to load unsigned extensions.

The fact that your extensions are loading indicates that either they were signed and installed, or that you have already enabled PlayerDebugMode for CEP12. 

The extra weird part is that your invisible extensions behave correctly, if you happen to click where their UI should be. 🙂

Do you see better/different behavior, if you enable PlayerDebugMode for CEP12?

[Maor5C10]

same 😞

[Bruce Bullis]

Are all the extensions you're testing, your own? 
Do you see different results with, for example, the PProPanel sample?

[Maor5C10]

Even this one is unvisible

[Bruce Bullis]

We have no idea how you got into this state. I'd recommend removing all PlayerDebugMode references (in the registry or .plists), remove and re-install PPro, and retest.

Hello. I can confirm this is a huge issue across all Adobe 2025 apps at present. I've tried Photoshop, After Effects, Premiere Pro, Illustrator, and Audition. The name of the CEP panel displays, but no UI. Why is this happening? Can Adobe please fix this bug?

The post prior to yours points to the problem description, and workarounds.

Sorry. I can confirm it is working with this work-around. My apologies.
