Troubleshooting steps

I saw some similar posts that suggested setting the following may help:

LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8

I tried this but it didn't resolve the issue.

@call the runner won't work on M1 or BigSur+ for now, dotnet core doesn't support it yet.

@TingluoHuang Do you know of somewhere where I can track Monterey support (not apple silicon) for dotnet core? Thank you.

Hi @call,
Since @TingluoHuang explained everything to you, I'm going to close this issue. Feel free to reopen this one or report new one if needed.
