Keep getting "Video playback interrupted. Please try again" when trying to view livestreams

Since Friday 8/2 I have been having trouble viewing livestreams on myy iMac (M1. 2021), as they drop out after a few seconds with the message "Video playback interrupted. Please try again." I have already updated Chrome and my OS, as well as cleared cache and restarted my computer and router. My connection speed is good (258.8 Mbps download/14.2 upload). I know I can get the stream to work on my phone and other devices, and Twitch runs without any problems. I have tried using other browsers like Safari and also a VPN connection with the same result. I don't know what else to try, and I'm not sure what caused it to begin with since it was working up until Friday.
