Any Recent Updates?

If so, then this may be a bug. So, contact these sites/channels and see if they have yet to do their part in compatibility. In the mean time, try reinstalling the macOS. It may not have gone through successfully....

2. Then, Reinstall the macOS:

Nothing would be deleted. It's just that items that have become corrupted or deleted, would be replaced or reinstalled back to where they should be. Go Here: How to reinstall macOS from macOS Recovery - Apple Support

Always Back Up:

Take this as a learning experience, knowing to always create a Time Machine backup of your Mac prior to installing and upgrade, so that you can have something to restore your Mac from, should anything go wrong with the transfer.

Router Streaming being the Culprit:

Sounds like a steaming issue. So, how fast is your router? Is it intended for streaming content? If not, upgrade your router to one that is.
