[Error - 1:42:36 PM] Request textDocument/inlayHint failed.
  Message: InternalError: panic handling request textDocument/inlayHint: Debug failure. Unexpected node.
Node KindPropertyAccessExpression was unexpected.

Steps to reproduce

Just open a TypeScript file containing disposer logic. Minimal Reproduction Code:

const func = () => {
  using _defer = {
    [Symbol.dispose]() {},
  };
};

Or

const func = async () => {
  await using _defer = {
    async [Symbol.asyncDispose]() {},
  };
};
