@EthanSK, for what is worth, I had the same problem (see #4887), and then I installed arm64 version of VSCode and removed the ~/.vscode/extensions/ms-dotnettools.csharp-1.23.16 folder. That made it download arm64 binaries (in addition to x64).

You can verify that you have them by checking ls -l ~/.vscode/extensions/ms-dotnettools.csharp-1.23.16/.debugger

@TomMurphyDev yes, it is extremely likely that the C# extension will release osx-arm64 debugging support prior to the official .NET 6 release.
