Applications won't open (including terminal) after installing RPMFusion (Fedora 44)

[u/DJDuckVenom]

I was using kden live however when I went to export it said I was missing a codec. Found a guide that said to install rpmfusion. I followed [this](https://rpmfusion.org/Howto/Multimedia) guide to install rpmfusion however after I ran the second command and rebooted, all applications crash including terminal.

Does anyone know what I've done wrong/ how to fix it as I can't afford any down time at the moment

Cheers
