OBS/Streamelements crashing

[KaosMunkey]

Hey all I was wondering if people could help me. Last few weeks OBS has been working great when I am streaming, but now for some reason my Canon 450D was having issues with talking to my OBS to use as my Just Chatting Camera, Once I got it sorted it I was working on my main camera NexiGo 1080p but for some reason it isnt showing up in OBS but when I am chatting on discord it shows my camera and people can see me (I deactivate it on Discord when using it on stream)
If anyone can please help me as soon as possible (I have done a fresh install)

Why did you mention streamelements? are your running StreamElements OBS, vs OBS Studio?

Streamlabs OBS [SLOBS] is a derivative version of OBS Studio, with the front-end hacksawed off and a webpage slapped over the top by the Streamlabs folks.

You should reach out to Streamlabs <https://support.streamlabs.com/hc/en-us> for support with their forked version.
If OBS Studio, follow pinned post (link in my .sig) in this forum on posting your OBS log
