Woocommerce coupons created under Marketing -> Coupons are no longer being accepted at the checkout. When a user enters the coupon code and clicks "Apply voucher", the page refreshes, a loading icon briefly appears over the order summary, then nothing happens. The total amount does not change.
I’ve reverted back to Storefront and disabled all plugins: the problem still persists.
An error on the System Status page told me that SoapClient was not installed on my server, but I have now installed this and the problem still persists.
If required for testing, this is the store URL and the valid coupon code 77qk2a9y should apply a 10% discount to the whole order.
The output of my system status report is as follows:

Found it. I'm using a plugin called Lucas String Replace to change various text strings around the site (mainly to switch Americanisms in plugins to British English). I'd set up a rule to replace the word 'coupon' with the word 'voucher' - presumably this was breaking some code somewhere.
Silly error. Posting this answer in case someone else encounters the same issue in future.
I tested with the js console open and if you analyze the respone you get from the server there’s this message:
I don’t know where that comes from but it doesn’t seem to be default Wc thing (tried searching the string in an empty woocommerce installation)
There must be something with one of your plugin but i don’t have any clue of which one it could be. Judging by the list u’ve pasted i would start from WooCommerce Gift Cards: by WooCommerce – 1.10.2
the coupon form is Elementor’s coupon form which is completely detached from the Woocomerce checkout.
Steps to fix – check Elementor template / remove the current coupon form bottom / enable coupon field in Elementor checkout widget
