Error when "Add to Cart" - Error message "We can't add this item to your shopping cart right now"

Hello,

I have the same error.

"This can be handled with config when setting the cache backend to file in app/etc/env.php" can you give an example, how to do it? What to write and where in env.php?

Thanks your solution worked for me for Magento ver. 2.3.4
