This is causing a CORS error. It looks like the specific string that triggers it is .." occurring anywhere in the code submission.

For example, this will work (note the .. in the second line):

List<int> xs = [1, 2, 3, 4, 5];
Console.WriteLine(xs[2..].Count);

But this will trigger the error:

List<int> xs = [1, 2, 3, 4, 5];
// .."
Console.WriteLine(xs[2..].Count);
