According to the Romanian Ministry of Foreign Affairs:
Given the conditions selected previously, you need a visa in order to travel to Romania.
However, should you fit into one of the situations below, you are exempt from the Romanian visa requirement, for stays that of no more than 90 days during any 180-day period:
...
• I hold a residence permit issued by a Schengen member state ;
“An essential precondition for the equivalence of these visas as Romanian national visas is that they be valid, namely that the right of stay and validity period not have been used up.";
Therefore the answer is no, you would not be allowed to enter Romania without a visa.

To clarify your status and answer some of the questions in the comments, the document you hold does entitle you to leave and reenter France. It is a valid residence document and listed as such in Prado. Service-public.fr also states that such a document can be used to return to France. Since the right of stay and validity period attached to your récépissé have not been used up, you should be covered by the rules allowing Schengen-area residents to enter Romania.
At the same time, because it is a somewhat unusual document, it's difficult to rule out some issues at the airport in Brussels or at the Romanian border. If the travel is not essential, it could therefore make sense to postpone it.
