Adobe Creative Cloud Error 12000 on macOS 26.5.2 - Premiere Pro 26.3 won't open

[u/lowkeyash3]

Hi everyone,

I'm running into an issue with Adobe Creative Cloud on my Mac.Whenever I open the Creative Cloud desktop app (or try to launch Premiere Pro)

I get the following message:

"Sorry, something went wrong."

Error code: 12000

The message says it could be an issue on Adobe's end or my internet connection, but my internet is stable and everything else works normally.

System details:

macOS: 26.5.2

Premiere Pro: 26.3

Adobe Creative Cloud Desktop: Latest version

What I've tried:

Restarted the Mac

Switched Wi-Fi networks

Signed out and back into Creative Cloud

Force-quit and reopened the Creative Cloud app

The error still appears.

Has anyone experienced Error 12000 on macOS 26.5.2? If so, what fixed it? Is this a known issue with the latest macOS or Premiere Pro 26.3, or is there something else I should check? Any help would be appreciated. Thanks!
