comment Need some help to break a cypher text using unknown cypher
We typically don't answer "could you please decrypt this for me" questions, however if you want advice on how you might decrypt it yourself, well, one place you might start is looking at Vigenere ciphers -- might this be encrypted with something like that? Those typically have flatter (but not perfectly flat) distributions like you're seeing.
