Photoshop Crashing on launch when connected to internet

[renaud5CFA]

Bonjour,
Depuis la mise à jour vers Photoshop 2025, le logiciel plante systématiquement au démarrage si ma connexion Internet est activée.
En revanche, si je coupe Internet, Photoshop démarre normalement et fonctionne sans problème.

Voici ma configuration :

• PC : ASUS ProArt Station D940MX

• GPU : NVIDIA Quadro RTX 4000 (drivers à jour)

• OS : Windows 11 Pro 64 bits

• Version de Photoshop : 2025 (v26.x.x)

• Creative Cloud : dernière version

• Aucun plug-in tiers actif

J’ai déjà tenté :

• Réinstallation complète de Photoshop

• Nettoyage du cache Adobe et réinitialisation des préférences

• Démarrage sans Internet → OK

• Démarrage avec Internet → crash instantané

Le problème semble lié à un service en ligne (peut-être la vérification de licence ou Adobe Sync).
Merci de votre aide ou d’un correctif éventuel.

@renaud5CFA This issue has been reported by other users and may be linked to version 26.4.x or later. Photoshop 2025 crashing at startup when connected to the internet is likely caused by a conflict with Adobe’s online services—such as license verification, cloud sync, or plugin validation. 

You could consider rolling back to Photoshop 2024 (v25.x) using the Creative Cloud app (if available). That what I would do! 

But, you can also try troubleshooting Photoshop crashing at startup when connected to the internet, you can begin by temporarily disabling Adobe Cloud Sync. Open the Creative Cloud Desktop app, navigate to Settings > Syncing, and turn off File Sync. Then restart Photoshop with your internet connection active to see if the issue persists. If that doesn’t help, try blocking Photoshop’s internet access using Windows Firewall—this allows you to stay online while preventing Photoshop from interacting with Adobe’s online services. Additionally, check for background Adobe processes in Task Manager before launching Photoshop. You might also experiment with disabling services like Adobe IPC Broker or Adobe Desktop Service to see if they’re contributing to the crash.

Hi @renaud5CFA,

Sorry to hear about the crash on startup — thanks for sharing all the details, that’s really helpful! Since Photoshop launches fine when offline, it indeed sounds like something is blocking its online connection, possibly a firewall, antivirus, or proxy interference. I am hopeful that the steps suggested above were helpful and helped you resolve the issue. If not, could you please share a few more details to help us narrow it down?

• Are you using any VPN, proxy, or firewall software (e.g., Windows Defender, BitDefender, Norton, etc.)?

• Can you check if adding Photoshop and Adobe Creative Cloud to your firewall exceptions helps?

• Try connecting to a different network, like a mobile hotspot, and see if that helps. 

• Could you also share your System Info from Photoshop (Help > System Info > Copy and paste here)?

Once we have that, we can look deeper to identify what’s triggering the crash.

Thanks,
Srishti
