Adobe Creative Cloud Collaboration Synchronizer (adobecollabsync.exe) Crashes

ControlUp’s Innovation Guild identified a recurring crash pattern in Adobe Creative Cloud, explicitly tied to the Collaboration Synchronizer component (adobecollabsync.exe). This background service is responsible for syncing shared assets, libraries, and collaborative content across Adobe applications.

Analysis of global crash telemetry revealed that the issue was primarily associated with specific executable versions, with the highest crash rates observed in adobecollabsync.exe versions 25.1.20918.0 and 25.1.20937.0. A significant reduction in crash frequency was detected beginning with version 25.1.20997.0, indicating a meaningful stability improvement in later builds.

The issue was detected through ControlUp’s global crash analytics, leveraging anonymized metadata across customer environments to surface emerging application stability trends at scale.

• Interrupted or delayed synchronization of Creative Cloud assets
• Inconsistent availability of shared libraries or collaborative content
• Reduced reliability across Creative Cloud applications that depend on background sync services
• Increased user confusion or support requests related to missing or out-of-date assets

• Review crash logs related specifically to adobecollabsync.exe
• Identify the exact executable version deployed across affected endpoints
• Prioritize updating systems running versions 25.1.20918.0 or 25.1.20937.0
• Apply the latest Adobe Creative Cloud updates, particularly versions 25.1.20997.0 or newer, where crash rates have materially decreased
• Monitor post-update crash trends to confirm stability improvements

This finding underscores the critical role of background synchronization services, often invisible to users, in modern creative workflows. When these components fail, the impact is felt across teams relying on shared assets and real-time collaboration.

ControlUp will continue monitoring this crash signature globally and share updates as new insights emerge. If you’re seeing similar Creative Cloud sync issues or have identified effective mitigations, community feedback can help accelerate understanding and resolution.
