CEP panel suddenly stopped working

[Matias Benamo]

my Premiere Pro stopped running any CEP panel..
i ve developed my custom panel from the ProPanel example i found around here, 

suddenly on friday, after monhts of development, they stopped working
It shows up in the menu Window > Extensions > but nothing happens when i click on it. 😞 
 
I tried reverting to older versions, i have at least 10 older versions to my panel that i have been writingfor the past few months but none of them work. 

I reduced the panel to a basic 'hello world' with no functions or  NOTHING at all.
Still not working... I asked my coworkers to test it and it still works on their computers.
I tried reinstalling premier pro, then the whole creative cloud... and nothing changed

i have no idea what going on, pls help!! 
ps.: extensions are authd with the command 

defaults write com.adobe.CSXS.9.plist PlayerDebugMode 1

Thank you in advance,

What changed about your system configuration, on Thursday? 🙂

The behavior you've described is 100% consistent with PlayerDebugMode not being enabled for the version of CEP in use by PPro. 

Did you recently upgrade from an old version of PPro, on that system? PPro 24.x ships with CEP11, so you'd need to enable debug mode like so (and then relaunch Finder):

defaults write com.adobe.CSXS.11.plist PlayerDebugMode 1

Yeah its definately something related to that authorziation of the unsigned extensions

Sorry i had the command wrong in the first post 
ive use the command suggested in the documentation of the PPro Panel 
https://github.com/Adobe-CEP/Samples/blob/master/PProPanel/ReadMe.md
Which is 

defaults write /Users/<username>/Library/Preferences/com.adobe.CSXS.11.plist PlayerDebugMode 1

 
But it definately behaves as if i has never been authorized
Shows in the extensions list but doesnt open up

The solution to this issue will be in figuring out what changed on your system, between Thursday and Friday. 

Did you upgrade PPro? [Related question: Do you have Creative Cloud Desktop set to automatically update apps?]

You also mention trying other extensions, so I wanted to confirm; does PProPanel show up correctly, once you've enabled PlayerDebugMode for CEP11 and (important!) restarted Finder?

[Matias Benamo]

Nothing was updated during those, days, not that i can remember, 
Thou im getting a msg i didnt get before while doing the 

defaults write /Users/<username>/Library/Preferences/com.adobe.CSXS.11.plist PlayerDebugMode 1

BEFORE i was able to do it without the need for 'sudo'
now, if i dont sudo the command i get 

2024-07-29 14:24:04.578 defaults[13398:123690] Could not write domain /Users/<username>/Library/Preferences/com.adobe.CSXS.11.plist; exiting

 It all seems very strange, im about to loose my mind

[Bruce Bullis]

That suggests you are trying to make that change, from within an OS user account that is not an admin of that machine.

[Matias Benamo]

Yup true!! But i do have admin rights, and managed to succesfully run the auth command with sudo, 
the behaviour is still the same, i cant believe im going to have to go to IT to get my  computer formatted to get rid of this weird bug!!

[Bruce Bullis]

You still haven't said whether the PProPanel example panel, loads successfully...?

[Matias Benamo]

Noup im afraid that one doesnt work either  😞 

[Matias Benamo]

Hey Bruce! I've tried downloading this other PPro Panel based extension called "Sortinator"
As you can see in the video, this one launches perfectly, with no issues,
Idk, it adds to the mistery. =/

[Bruce Bullis]

Wow!

[Matias Benamo]

any other ideas Bruce? pls i need help on this

im all ears 

[Bruce Bullis]

None, sorry.

if an unmodified PProPanel fails to load, then PlayerDebugMode is not properly configured on your system.

you say you have enabled it for CEP 11; if, after restarting your system, the panels still do not load, that would be the first instance of such a failure since CEP support began in 2013.

in desperation, I might try deleting all CSXS-related .plist files, rebooting for luck, then setting PlayerDebugMode again.

I've attached a video with what im dealing with, tomorrow im going to take my mac book to the IT department,
but im sure they wont know what to do and suggest i do a format/reset of the OS
but i want to exhaust all options before doing that 🙂 

[Matias Benamo]

Yes sorry i do have the auto-updates ON in my CreativeCloud app,
