Sitecore Forms not loading on first load

Question

We have created Polls for our application using Sitecore forms. The rendering we have created to load the poll have set of personalization rules. On first load, form is not loading. Instead it throws 404 page. If we are refreshing the page, form is loading properly.

Below is the implementation that we have followed.
1.Designed sitecore form for Poll with radio button and save data submit action
2.Created controller rendering in Sitecore and mention controller and action name respectively
3.Added the controller rendering in the layout
4.Added personalization rules in the rendering to target context datasource
5.Added "Mvc Form" rendering in the layout.

In view, called the Form.cshtml as below

@model TestProject.PollData.PollViewModel
else if (Model != null)
{    
    <div class="col-md-6 col-lg-6 col-xl-4">
        <div class="card mb-4">
            <div class="card-header">
                Polls
            </div>
            <div class="card-body pollSurveryForm">
                <h5 class="card-title">How would you rate our experience?</h5>
                @Html.Sitecore().Placeholder("/Layout/HomePage/phFormContent")
            </div>
        </div>
    </div>
}

Form.cshtml will be loaded in the above mentioned placeholder.

@{
    using (Html.BeginRenderRouteForm(Model, IsPost))
    {
        @Html.AntiForgeryToken()
        @Html.Hidden(AttributeNames.FormItemId, Model.ItemId)
        @Html.ValidationSummary(true)
        @Html.RenderFields(Model)

        <script type="text/javascript">
            (function($) {
                var $formEl = $("form[data-sc-fxb='@Model.ItemId']");
                if ($formEl.length && typeof $formEl.init_fxbConditions === 'function') {
                    var options = @Html.RenderConditions(Model);
                    $formEl.init_fxbConditions(options);
                }
            })(jQuery)
        </script>
    }
}

But the issue is Form.cshtml is NOT LOADING on first load. We have to refresh/reload the page, then Form.cshtml is loading with correct form.

Personalization rules in Sitecore:
