Plugin not loading with AMD gpu

I had a webm plugin installed and working fine with Premiere Pro 2024 and a GeForce RTX 3060 Ti. When I removed my GPU to use my Ryzen 5 7600's RDNA 2 integrated GPU andTHEN  booted Premiere Pro, the program first asked me to select at least one option to clear before loading into the program. I selected to clear media cache and plugin cache then found my webm plugin not working. I reinstalled the plugin, Premiere Pro, made various registry tweaks, and it still will not work.

So I wonder if Premiere asked me to clear something because it found an incompatibility with the AMD GPU? Is it possible that the webm plugin doesn't work with AMD GPUs, or can I fix this?
