[2025.31310] Win11 NDI Out

My project crashes on load, I get a popup suggesting rolling back NVIDA Drivers to 555.xx. If I open the project using ‘CrashAutoSave’ and remove the NDI out, the projects opens without issue. Any suggested fix, do I actually need to roll back my drivers?

Win 11 Pro
OS Build 26200.6901
NVIDA GeeForce DTR 3080 Ti Laptop
Driver Version 573.57

Strange that this worked yesterday, but doesn’t this morning. Windows does not report any overnight updates.

Hi @jfarrow,

do you have a TouchDesigner dmp file that is created from this crash? If this is repeatable, can you share the project file or a minimal reproducible example?
Could you see the crash is still happening in our latest official release?

cheers

I’m mapping an OP Viewer ( using me.parent() ) to an NDI out.

This constantly fails in my network, but not in a new blank file.

The error dialog doesn’t show any issues. Any insight would be appreciated.
