not working for some products

Hi,

The instock notifier is not working for some products.
I get the error: something went wrong blablabla.

I foud different solutions like recaptcha V3 + V2, change the wordpress ajax to the other API but nothing is working.
I also tried creating a new product…
Enabling and disabling the extension…

Does someone has another solution.

I use total cache and flushed the cache each time I tried a solution.

Thanks for your help.
Kind regards!
