Do you have the same issue with the image dialog or any other TinyMCE's own dialog? If so, I suspect you have a focus trapping issue where the modal, on which tinymce is loaded, trap the focus within itself, making TinyMCE's own dialogs uneditable or unfocusable. Try this approach

document.addEventListener('focusin', (e) => {
  if (e.target.closest(".tox-tinymce, .tox-tinymce-aux, .moxman-window, .tam-assetmanager-root") !== null) {
    e.stopImmediatePropagation();
  }
});
