Error when trying to access the list of products from the backend

Hi
I have updated the site from Joomla 3.10.12 to Joomla 4.4.8 and since then I have not been able to access the list of products from the backend of the site.

I discovered this because from the front end each category I try to access gives me a 404 error, I assumed it was because of the update and that I had to create new product categories, but when I tried to change the category of the products from the backend, I could not access.

I really appreciate your help in solving both problems.

Hi

I am attaching screenshots of the error screens both in the backend and in the front of the site.
I did some research into what could be happening, among the tests, I disabled the HikaShop Like plugin since it was the first thing that appeared in the stack trace and it would seem that the problem is with that plugin, since if it is disabled the error stops and I can access the list of products in the admin and all the categories and products in the front.

Can you help me with this plugin? I don't remember what its specific function is, but if it is available it should be useful.

Thank you very much!

Hi

Thank you very much, I didn't remember that it was a separate plugin from the hikashop core component
