Azure/bicep] Launching server using command X failed

I was redirected here from the Bicep extension or VSCode

Does this occur consistently? Yes
Repro steps:

Start VScode (with extension installed and enabled)
Open a .bicep file

Expected:
Normally the language server would start and you would be able to use intellisense with bicep.

Actual:
The server fails, no matter where you install .NET and were you manually point it to. (at least in my case)

Notes:

This is on an Apple M1 processor in an Apple Macbook Pro.
The automatic installation of .NET fails, have to install manually.
The automatic installation failed during the startup of the ARM template language server as well, but after manual installation and pointing to the dotnet binary, the ARM template server works fine.

Action: bicep.activate
Error type: string
Error Message: Launching server using command /usr/local/share/dotnet failed.
