Error [Ajax / Server Error for action unzip] textStatus: "error " errorThrown:" " jqXHR: " " while doing 1-click upgrade

Hi i have a problem with saving changes in products, the page is kinda wanky and jacked, it happend after a month of not touching anything. You cn se the error "The CSRF token is invalid. please try to resubmit the form".

I tried upgrading prestashop to a new version but another error prevents me from that. [Ajax / Server Error for action unzip] textStatus: "error " errorThrown:" " jqXHR: " "

I am not good at coding so please propose solutions if you have any, like you would to a child.

Thanks :)
