Could you please check if this is the form URL that you have been trying to submit:

If yes, there looks to be a few errors on the form's condition page.

Could you reach out to the form owner to check and rectify those?

When I cloned and tested that form, it submitted fine.

While filling the form, did you fill and submit in one go, OR did you click on Save and submit the form at a later time?

As mentioned in my last response, could you reach out to the form owner?
