I believe the fields root_hash_use_sparse_trie and root_hash_compare_sparse_trie are commented out in this config. See the lines

# fix: Error: root_hash_use_sparse_trie=true and root_hash_compare_sparse_trie=false must be set, otherwise node will produce incorrect blocks or confusing error messages. These settings are enforced temporarily because upstream parallel root hash implementation is not correct.
# root_hash_use_sparse_trie = true
# root_hash_compare_sparse_trie = false

It should work if you uncomment the 2 lines.

@ferranbt please correct me if I'm wrong
