Question / Help NDI plugin with Skype crashes everytime I try to add the source


New Member
I have macOS 10.13.6 High Sierra, OBS studio 24.0.6 (64 bit)
I have today installed NDI plugin and runtime.
The NDI appears in my source list - I add to the scene.
I have my Skype call already running (I can see the video).
I select under Source Name .... well it's hard to know, there are several options, but I choose any of them and then click OK, OBS crashes.
(I never see anything in the window above Source name....)
The various sources start with my Computer name then .LAN then
> ([Skype - live]-usernameoftheotherpersononskype)
> (OBS)
> (Skype - (Local))
> (Skype - active speaker)

If I choose any of them then press OK, OBS just crashes.

Does anyone know what is causing this or how I fix it?

I am trying to do a livestream with my own webcam and two international friends calling in on Skype.

Thanks so much for any help you can offer!
