How to remove freeze webpage after closing the swal?

Here I am closing the form after form gets submitted successfully with all required fields .
But inside that submit function there is Swal (alert) for confirmation . But after clicking on swal OK button my webpage gets freeze and didn’t respond

const handleCloseModal = () => {
document.getElementById(“modalid”).classList.remove(“show”,”d-block”);
document.querySelectorAll(“.modal-backdrop”).forEach(el => el.classList.remove(“modal-backdrop”));
}
added this function inside the onSubmit function
