Premiere Pro 25 plugin can't be loaded

[broadcastingengineer]

Hello,

I am currently using a plugin built on the CEP framework with Premiere Pro versions 22 to 24. As I am testing the environment to update Premiere, I found that the plugin does not run in Premiere Pro 2025.

Would the execution error report be stored in the UXPLogs_date.log file located at $HOME/Library/Logs/Adobe/Adobe Premiere Pro 2025?

Additionally, I understand that Photoshop and InDesign have already transitioned from CEP to UXP. I would like to know if Adobe has plans to transition Premiere Pro as well. Since I need to develop accordingly, it would be helpful if you could provide an official roadmap regarding this transition.

Thank you.

Did you make sure to enable debugging for CEP 12? Maybe it is only running on older Pr versions, since older versions rely on older CEP versions, and maybe you have debugging enabled only for those?

Concerning UXP and Pr see here:

After enabling debug mode using the command:

defaults write com.adobe.CSXS.12 PlayerDebugMode 1

the plugin launches but then an error message appears, and the plugin closes.

I would like to know if I can check the issue in the log files. Additionally, from Premiere Pro 25.1.0 onwards, does CEP no longer work, and only UXP is supported?
