To those using Tube Archivist, does it often freeze for you too?

I'll start by saying that I really love Tube Archivist. It works flawlessly in doing what it does (archiving YouTube videos), and the UI and UX are great.

However, no matter what browser I use (Edge, FF, Opera, Samsung mobile, FF mobile, etc...), I run into issues where the video will play, but the interface freezes... I can't do anything on the screen until I refresh.

I don't have it set to any strange codecs, so videos are in vp9. But I also tried a few different codecs to see if the quality/size could be better optimized, and had the same issues with freezing UI then.

If I run the videos through Jellyfin, they work fine. It's only through the TA web interface where things lock up.

Is this normal? Does anyone have any suggestions on how to get this working better?
