The short answer is manpower.

Long answer depends on what you mean by working. Go produces very 
large binaries, and C# currently works by emulating dlls in your 
browser. TinyGo is an option but doesn't support the full 
language [https://tinygo.org/lang-support/]. Rust is the most 
mature, mostly because it doesn't have a runtime to port, so it 
is a lot easier.

With D the main issue is that someone needs to port druntime to 
wasm. I am working on it in my spare time, but progress is slow.

Here are some examples of what I have got running:

https://skoppe.github.io/spasm/examples/todo-mvc/ -> famous 
todo-mvc
https://skoppe.github.io/spasm-imgui/ -> use c++ library
https://skoppe.github.io/spasm/examples/underrun/ -> ported js 
game
https://skoppe.github.io/spasm-tradingview-example/index.html ->  
calling typescript
