jQuery is not defined

Hi,
I have a problem on one of the pages. I have many similar solutions, i.e. Gridbox + Hikashop, but this is the only one where this problem occurs.
First of all, I received information from the server operator that CPU resources are exceeded several times a day.
I checked various combinations, but I did not find a solution - that's why I am asking you to find the cause.
Attached is a screenshot of the error that occurs in the console.
