Checkout button does nothing

Hi, I am currently working on an e-commerce website for a restaurant. It is only click and collect, so no shipping required on any of their products.

I have been doing some research and it seems that the bug is known… (at least) since 2019…

If someone could help, that would be very much appreciated. Here are some links that might help you help me. Thanks in advance!
