Touchdesigner not responding as long as I connect CHOP to TOP

I just updated the newest touchdesigner but it always freezing as long as I connect a CHOP to TOP.
I have contacted the dell tech support and updated the driver to the newest. The problem still exist. Dell suggests me to contact touchdesign support.
Anyone could help me ?
Thank you so much

Hey @xinyelin

Does it just freeze or are you getting any error message if you force quit the process ? or .dmp file ?

Could you please share the complete specs of your machine, especially the GPU? Feels like something is missing in what you shared. Do you have an Nvidia GPU ? If yes, what is the Nvidia Driver version ?

Hey @xinyelin

Thanks for sharing these.

Can you please have a look at what GPU Driver Version you are using ?

When opening the Nvidia Control Panel, you see it on the first page.


Hi Michel,

Thank you for replying, I just checked it.
my GPU Driver Version is 516.94, exactly your screenshot.


Hey @xinyelin

It feels similar to the following issue Crash when i make a reference / The Vulkan Device has returned a fatal error code - #46 by

Could you please try to downgrade your GPU driver and let us know if that solved it ?

If that doesn’t help, could you possibly look into any “bloatware” installed on your Dell computer? such as some kind of “Alienware Control Center” or something of the sort?


Hey Michel, it works!! Thank you so much !
