Indesign freeze without crashing when calling app.doScript() from a UXP plugin

Why does InDesign freeze when calling app.doScript() from a UXP plugin? Not always, but every other time. I can’t get a crash report because indesign doesn’t crash, it just freezes for a long time. InDesign v19.0.

const script_name = "Clear Overrides"

app.doScript(
          clear_overrides,
          ScriptLanguage.UXPSCRIPT,
          [],
          UndoModes.ENTIRE_SCRIPT,
          script_name
        )

function clear_overrides() {
    console.log("Starting Clear Overrides")
    try {
      const stories = get_stories(doc)
      for (let s of stories) {
        if (s.textContainers[0].parentPage.parent != "[object MasterSpread]") {
          s.clearOverrides()
          s.footnotes.length &&
            s.footnotes.everyItem().texts.item(0).clearOverrides()
          s.tables.length &&
            s.tables
              .everyItem()
              .cells.everyItem()
              .texts.item(0)
              .clearOverrides()
        }
      }
    } catch (err) {
      console.log(err)
    }
  }

function get_stories(range) {
  try {
    if (range.constructorName == "Document") {
      let all_stories = range.stories.everyItem().getElements()
      let stories = all_stories.filter(
        (s) =>
          s.textContainers[0].parentPage &&
          s.textContainers[0].parentPage.parent != "[object MasterSpread]"
      )
      return stories
    } else {
      let story = range.parentStory
      return story
    }
  } catch (err) {
    console.log(err)
    return []
  }
}

@koganalexey The script had few parsing errors, which I fixed and ran several times. I don’t see the issue reproducing at my end. Are you able to reproduce it consistently with the above script alone?
