i just tried to reproduce this (on window 11, though) and am not experiencing this...can you try this on another machine, or maybe a faster network connection and then re-report...thank you!

Yes, I posted this issue because I’ve experienced the same thing in the school's computer room. A few of them are still running Windows 10. However, since I see a spike in CPU usage, I’m guessing it might not be related to the network?
