I just missed adding this to bug 1787546 before it was closed, but it's similar:

function f() { throw new Error("bleah")}
let e;
try { f() } catch (err) { e = err }

console.log(e.stack);  // has the stack you would expect...
console.log(structuredClone(e).stack);  // empty string??

This should work, unless you are doing this on a Worker thread.

Oh whoops, this does look like a duplicate of 1774866. fwiw, my particular use case is exactly sending an Error from a worker to the main thread with postMessage but it looks like you're already on top of that.
