According to your description, I suggest you could write another condition to check if the page is not goes to the account/login. Like below:
Notice: If you use default identity, the url path should be /Identity/Account/Login , so you should check the request path is it. Besides, I suggest you could directly use location.href = "/Identity/Account/Login" instead of "@Url.Action("Login", "Account")" , since it will generate a wrong url if the account controller doesn't contains the login method. This will also cause the Infinity loop.
<script type="text/javascript">
window.onload = function () {
if ('@HttpContextAccessor.HttpContext.Session.GetString("username")' === '' && '@HttpContextAccessor.HttpContext.Request.Path' !== '/Identity/Account/Login')
{
location.href = "/Identity/Account/Login";
}
};
</script>
