[BUG] Blank Video Thumbnail After Converting Video.

[Anomoly]

I just upgraded to Hybrid 2017.10.05.1 (for Windows) after the previous version stopped working. With the new version, everything was working perfectly well, except when I convert a video, the thumbnail of the converted video ends up being blank for some reason. The previous version didn't have this problem and now I'm left with no other choice but to ask for help in this forum. The video is able to play just fine. It's just the video thumbnail where there's suppose to be a picture of the video is missing. I provided an attachment so you can see the problem. Hope you can fix this right away.
