I assume the NDI installations changed some configuration and that's why OBS won't run. I have zero familiarity w OBS, since I just installed it and was taking a peek around, trying to get sources to connect. I did have it running and it recognized the NDI source (my iphone cam) in the source list, but didn't actually stream it to the canvass. Something happened and OBS crashed. Won't start ever since. Have deleted all the NDI tools (although I know I installed 5 and only found 4 to delete, so somewhere there is something I haven't removed) and deleted/reinstalled OBS. Don't know where the NDI plugin is stored, if that is what is crashing OBS. Not sure how to attach full crash report, but here's a screenshot. Thanks for any insights you may have.
