What happens is that the RAM usage, CPU usage, and Network usage would spike up dramatically with this plug-in enabled. Then YouTube would crash 2-3 minutes later, saying, Oh Snap, ran out of RAM usage. I can use Chrome fine when disabled though. It only started happening this morning, was not happening before
For my specs, I am running an AMD Ryzen 7 3700X, 32GB DDR4 @ 3600Mhz and an Nvidia RTX 2070 Super
Experienced the same issue today. Heavy freezes and high resource usage while the extension is active on Chrome. Disabling it fixes the issue for now.
I confirm. I’ve been having problems all day using Youtube, never mind watching a video. It’s fixed after disabling the Language Reactor extension. Please work on it, I love this project.
Also having an issue. High resource usage and crashing, only for YouTube so far
exact same problem, I will be disabling this extension until it gets fixed
Update, it seems to be pretty random. If you disable the extension and then re-enable it after a while, it will work fine until the next time you restart your PC then you’ll run into the same issue again.
I tried disabling the extension, but this issue still happened. Only after completely removing the extension could I watch YouTube again. Or I had to use an Incognito Tab… 
I also had this same experience. I really love this extension for Netflix, however having to disable it so that I can use youtube for music is a little inconvenient. Really appreciate all the work put into this, as it’s so helpful for my learning.
