"I can't understand what it means" is an indirect question. You need to use a direct word order, like in a statement, after what/when/where/if/etc.
"Can you tell me where the bank is?"
"I was wondering how you did that. "
If you really want to use your first example, you need to separate it into two distinct sentences: "I can't understand. What does it mean?"
The second one (I can't understand what it means) is correct.
The first one is not correct and would not normally be used by a native speaker. However, a native speaker might say or write something that sounds very similar:
The phrase what it means can be used as part of another sentence, to indicate what the thing is that you don't understand.
The question What does it mean? is a complete sentence by itself, and can't be used as part of another sentence (except of course as a quote - She looked up and asked me, "What does it mean?")
