Cannot add to cart in v9.12.4+

I am having issues with adding to cart after updating to v9.12.4+ (also tried v9.12.7). I have already updated other projects and they do not encounter this problem, so it's exclusive to a single project. After updating nothing gets added to the cart and it will remain empty.

The screenshot below is of the same project but with v9.12.3 and v9.12.4, it seems the LanguageId is missing in v9.12.4.
I do have the entire ?debug=true log to share if needed, but this is what I think is most likely causing the issue after the update.

Any ideas what may be causing this? Why it only seems to be occuring in a single project and not others?

Kind regards

Hi Natan,

Some bug related to the product language ID seems to be in code on last DW versions. I've created new task 6367. It will be fixed in an upcoming DW release. Thanks for finding and sorry for inconvinience.
