Spontaneously it would seem that the file system is glitching. LiteCart attempts to create cache subfolders if they are missing. But when creating it your file system indicates that it already has been created. I would ask the web host what could be the cause of it.

Thank you, dear Tim, for your response. I will contact the host regarding this.

This is the code, and my comments to what is happening

            if (!mkdir(dirname($cache_file))) { // <--- Directory is created but fails with error directory is already created
              trigger_error('Could not create cache subfolder', E_USER_WARNING);
              return false;
            }
          }```

Do I use this code or is it just for clarification? If it is used, where is it placed?

That's just for clarification. It's the code from ~/includes/library/lib_cache.inc.php (Line 259)

Thank you for your interest and following.
