The log file has no streaming attempt. You have to do a test stream of no less then 30 seconds, doing as you normally do.
Now stop the stream (do not close OBS) and upload/analyze the log file. Copy the URL in here too.
Make sure you have removed any plugin you may have installed.
I read through that log file, caught a name spelled wrong I never noticed until now.
It appears all the webcam links work without a crash, it is the weather radar link, however, that is a different story. I deleted the original scene and recreated a new scene and tried again. As long as I do not choose that scene, OBS does not crash.
There is something at
https://www.wunderground.com/wundermap It is that scene that is crashing OBS, to which it never did that until the 15th of December, which is where OBS created its 'first ever' crash report. It never crashed it in the past.
I have changed a few things in the scene properties window, the drop-down menu called Page permissions. Choose 'No access to OBS' to 'Full Access to OBS', no changes with that scene not causing the OBS crash, it crashes no matter option I set it to.
As for plugins, I am not sure if Intel added a new plugin with the newest update. I suppose I can check to see what plugins that were installed recently.
