Can't add new product

[Marcel1987]

Gentlemen, I'm green on databases. I have Prestashop 1.7.6.5 and unable to add a new product. After clicking Add New Product it crashes to the backend dashboard without any errors. I think it happened because I installed a template that I bought for 50 Euro. I did a DB optimization in phpmyadmin and it still doesn't work. Please help.

Hello Version PHP: 7.1.33

In debug mode i have screens:

[Razi]

1: how many total products you have
2: you update the prestashop version or import data ?

[Marcel1987]

I  have about 3000 products import from xml importer. I didn't update presta. This is new shop.

Kindly check in DB table products, is there any id 4294967295 record exist?
if yes then also checked what is the previous id product of this record.
