Can you try setting the svelte.language-server.runtime? This would use your own version of node instead of the bundled version of vscode. If that doesn’t work maybe you can try to install the latest version of the node. I suspect it’s sourcemap or some other native library not compatible with the combination of node and macOS.

Wading through the issues above: This seems to be an upstream bug with V8 on ARM under macOS.

Rosetta2 is a viable workaround, either by running an Intel build of VSCode and using its built-in runtime, or using an ARM version of VSCode and pointing svelte.language-server.runtime at an Intel version of the Node executable.
