App updates consuming all bandwidth

Just recently, when app updates appear in the Creative Cloud app, if I click to update one of these apps, I'm unable to use the Internet for anything else on this PC while the app updates.

All browsers when loading web pages become excruciatingly unresponsive and most after some delay display "web page took too long to respond" errors.

If I cancel an update, or once it's finished, the web speed appears to go back to normal. The speed is only noticeable on this PC during the updates. Other devices on the network work as usual.

Is it possible to throttle the amount of bandwidth used during the update process so that I'm still able to continue doing other online tasks?

I've gone into Preferences > Creative Cloud > Files and changed the download and upload speeds, but this has no effect (as I believe this is a sync speed for files / assets).
