Photoshop refuse de fonctionner correctement lorsque je ne suis pas connecté sur internet ?? J

Try the following steps:

• Disable third-party plugins: Hold the Shift key while launching Photoshop to disable plugins, which often stops offline freeze loops. 
• Disable the Home Screen & Cloud sync: Go to Edit > Preferences (Windows) or Photoshop > Settings (Mac) and turn off features that try to reach Creative Cloud services on startup.
• Check Offline AI load: If you are using on-device neural filters or offline AI tools, they rely entirely on your local CPU/GPU rather than the cloud, which can cause heavy lag on unsupported or busy hardware.
