Hello @wassimj - was this a complex Python node, or a simple one? Are you able to upload a reproducible graph for us to test on?

[wassimj]

Hi @Amoursol. It crashes on a one-line trivial script. Just create a single Point.ByCoordinates(0,0,0) and try to label the python script. as in:
OUT = Point.ByCoordinates(0,0,0)

[mjkkirschner]

@wassimj - is this a new machine? Is this a new install of windows? Is it really windows NT? Is directx installed?

[wassimj]

Hi @Amoursol. It is a very new machine Dell Latitude 5580. Don't be fooled by "Windows NT".. This is what is reported in the crash report, but it is the latest Windows 10. Yes, I have DirectX installed. Here is the information:

[Amoursol]

I've used the same daily build - cannot reproduce the issue (Clean build - no packages), so it appears that something is conflicting.

[mjkkirschner]

@wassimj what type of GPU ? can you confirm you have set sandbox to use high performance mode (the discrete gpu)

[wassimj]

Hi @mjkkirschner and @Amoursol . It has an NVIDIA GeForce 930MX. It is set to use high performance globally. Here is a link to the video of the crash:

oh and in the video, I have chosen to hide the grid. It is not because of the video card.

[wassimj]

For installed packages, I had:
Graphical
MeshToolkit
SpaceAnalysis
Topologic

I removed all of them, restarted Dynamo and tested again, and it is still crashing.

[mjkkirschner]

@wassimj ah - this again... please try installing:
https://www.microsoft.com/en-us/download/details.aspx?id=8109

we have moved to include dx compiler 43 but apparently the billboard shader also needs the effects framework dll - ugh. Thankfully, when we pull in our references to a more modern helix version this should no longer be a problem, for now please try installing that older version of directX, it will not replace your new one.

[mjkkirschner]

checking in on this - did this workaround help?

[wassimj]

Hi Michael

Sorry. Got distracted with other tasks. Will check today.

[wassimj]

Hi @mjkkirschner and @Amoursol. Yes. Installing the older version of DirectX worked. It now shows the label without crashing. Thanks.
