Davinci resolve 18.6.6 , media does not work

I have got Resolve working on a Fedora 40 system with an AMD GPU by ensuring the right packages were installed and plugging in either a legitimate monitor or a ‘HDMI dummy’ into my eGPU.

First let’s ensure you have all the right packages with:

sudo dnf list installed '*amd-gpu*' '*amdgpu*' '*rocm*' '*roct*' '*hsa*' '*mesa*' '*vulkan*' 'kernel' | grep -v 'procmail|setproctitle

My packages are as follows:
