WebAssembly Error Parsing JSON at 1:1

[sschmitz98]

I've been stuck trying to get Qt Creator 8.0.1 to compile a WebAssembly project for a while now. It always gives a bad output from my C:\Qt\6.3.2\wasm_32\mkspecs\features\qt.prf:323 file, or the relevant version

It was previously working, but one day when I opened Qt Creator after switching from Desktop, my WebAssembly no longer seems to work and I can't recall what I would have done to cause this
I've tried creating new projects
I've tried WebAssembly 6.3.2 and 5.15.2
I've tried different versions of Emscripten (right now emsdk 3.1.6)
I've uninstalled and reinstalled all of my Qt programs

This is where the error is occurring in qt.prf

Is there something in the setup that I forgot to do this time but I did the first time? I'm just confused why a clean install doesn't fix my issue and am struggling to find similar cases online
