Description of the problem

Unable to run codesandbox.io cloud workspace on my local machine via vscode. I've got the VSCode Codesandbox extension installed and logged in but it gets stuck at the following output whenever I try creating a sandbox locally or via cloud.

Opening sandbox in VSCode, sandbox 6vzdsm
Fetching sandbox...
Installing SSH keys...

There is no output after this line in codesandbox terminal.
I can see ssh keys at ~/.ssh/csb/* and the same included as the following in my ~/.ssh/config.

# CodeSandbox SSH Integration
Include "csb/config"
# End of CodeSandbox SSH Integration

How has this issue affected you? What are you trying to accomplish?

I'm trying to run the cloud ( web ) codesandbox.io workspace on my local mac laptop using vscode so that I can install recommended extensions and work natively as I'm used to developing in vscode. Due to the issue, I'm unable to use vscode and am forced to use the web version of codesandbox while working.

Platform Details:

VSCode: 1.84.2

In case the following helps:
~/.ssh/config - 600 permission
~/.ssh/csb/config - 644 permission
~/.ssh/csb - 755 permission

To Reproduce

Link to sandbox: link (optional)

Your Environment

No repository file or test is named. Start by reproducing the linked sandbox through the VSCode Codesandbox extension on the reported macOS and inspect the SSH setup around ~/.ssh/csb/config; done means the workspace proceeds past “Installing SSH keys” and opens locally.
