This typically happens when the Universal version of VS Code is installed and runs under Rosetta. You may want to try uninstalling and downloading the Apple Silicon version.

[davidpene]

Thanks for the quick response @JoeRobich.
I'll try that and let you know how it goes

Additionally, I've seen the marketplace randomly installing the x64 version even on an arm64 version of vscode. One potential workaround is to uninstall the extension, then go into the extensions folder and actually delete all the ms-dotnettools.* versions for the wrong platform.

[davidpene]

I tried both and it looks like it worked, thanks!
I still can't seem to navigate using "go to definition" etc though, which I thought this would have fixed 🤷

[dibarbet]

Closing this issue as the original problem is fixed. If you're still having issues with go to definition, please open a new issue (and include the c# logs and general repro steps).
