Hello D5 Team,
I’m experiencing a critical issue where D5 crashes instantly whenever the Windows file save dialog opens, making it impossible to save renders or any files.
Symptoms
- As soon as the Windows file explorer / save dialog appears, D5 freezes briefly
- The dialog becomes unclickable
- D5 then closes automatically
- This happens before saving, regardless of render settings
- The issue occurs 100% of the time
- It affects all projects, including new empty scenes
At this point, I cannot save any files at all because the crash is triggered solely by opening the file dialog.
System Information
- OS: Windows 11 (latest updates installed)
- GPU: NVIDIA RTX 5080
- GPU Driver: Latest NVIDIA driver
- D5 Version: Latest version
- This is not project-specific
What I’ve Already Tried
- Restarting Windows (multiple times)
- Reinstalling / updating GPU drivers
- Switching GPU performance settings (Windows Graphics Settings → High Performance)
- Disabling Explorer previews and thumbnails
- Forcing legacy file dialogs via Windows registry
- Disabling overlays (NVIDIA Overlay, Xbox Game Bar, etc.)
- The crash still happens the moment the file save dialog opens
Conclusion
This appears to be a system-level conflict between D5, Windows 11’s file save dialog, and NVIDIA RTX 50-series drivers, rather than a project or user configuration issue.
At the moment, this issue completely blocks any workflow, since saving files is not possible.
I would appreciate guidance, confirmation of a known issue, or any workaround from the team.
Thank you for your support.
