Just so you know, your Windows 10 version is almost 2 years out of date. In other words, it has been depreciated and is unsupported.
I see a download attempt once, but you paused it, which caused it to be canceled. I don't know anything about OnlyFans, so I don't know if this is normal, but it looks like you were trying to download a forum post there, rather than a video. Maybe that's why you paused it. The rest of the log shows you replying to the post. I don't see any reason for the stoppage other than your own pausing of the download.

I downloaded a video from Onlyfans. After clicking on the download button, I can analyze it normally and start downloading. After downloading for a few seconds, it will stop downloading. After pausing, it will display 'cancelled' and restart downloading. I have tried restarting my computer and reinstalling streamfab many times, but to no avail
