I believe this coincided with my upgrade to HS. YouTube videos will not play. They just give me the old Ouroboros in the middle of the screen, but won't play.
Also, sluggish system in general.
I talked to Support. They think it's a YouTube issue. But I don't think YouTube would make my whole system slower.

Having one anti-virus program installed is bad enough. Having three installed is horrendous. You should uninstall all of them. Macs don't need anti-virus programs and they cause more harm than good.
Try booting into Safe Mode and see if the videos play.
Use safe mode to isolate issues with your Mac - Apple Support
No, YouTube wouldn't make your system slow down. Have you tried browsers other than Safari?
Sadly, yes. Firefox, etc... same thing.
Please install EtreCheck and post the report.
YouTube will not play
