Urgent can't add to cart / buy buttons greyed when selecting a variant

[contactdaiquiri]

Hi everyone I really need help on this one, my clients can't order my products. 

There are 3 products that are impossible to add to cart (no entry widget showing) once the customer selects a different variant (size). The buy button is greyed. Even the initial default size can't be selected anymore once you start clicking on the variants. 

In the same Collection, 1 product is working fine though, the 3 others display this bug (which would suggest it's not related to the Template ?). 

Inventory is full, other products from other collections are all fine, I don't know what's happening. 

Theme : Dawn 6.0.2

Hello @contactdaiquiri 
The line-item-property__field ( https://prnt.sc/UR-cBKjYDTnZ ) is missing on this product that's why the JS is causing the error on the variant change & the buttons are disabled on variant change.

Hi there @contactdaiquiri!

It looks like you've gotten some feedback from the Community here already, that's great!

I took a look at your store using the link shared here and was able to reproduce the behaviour you reported.

One thing you can look into doing is rolling back changes to your theme files to see if that might undo any recent changes leading to this issue.

You can see how to revert to a previous version of a .liquid file here on our help site.

Would you have added any apps recently or made any changes to code in your theme, especially around the product page or cart?

If so, you can try deleting any such apps as well as the code they would have added to your theme.

You can get support for this by contacting the developers of any app added to your store.

If you're in need of time-sensitive or account support, you can reach out via our Help Centre here where we can access and discuss your account with you.

We are experiencing the same Issue on for instance https://www.eldstad.se/products/rizzoli-vedspis-s80-svart. This is really not good! Please give valid solution to this issue.
