Every time I use Zoom, my internet connection crashes

[KitFlemons]

Every single time I use Zoom, it crashes my internet across all devices.
I still have Wifi - I can login to my router - but no internet on any devices.

This only happens when using Zoom.

I have restarted my router, restarted computer and my network card, and tried splitting my connection into 2,4 and 5GHz networks. I've updated everything, nothing works.
Please can somebody help me?
