After upgrading Magento 2 version 2.4 to version 2.4.1 I started meeting with issue - screen attached or link here: http://mage2.kouzloloutek.cz/z-ceskych-pohadek The issue is always appear when I want to get to product category.
My developer did re-indexing from terminal several times and also updated cron code https://prnt.sc/w7pun1 . It works fine, let's say a day, but suddenly the issue appears again. Could someone help, please?
Thanks a lot.
