PyPy Version: 3.8.16
OS: macOS (Apple Silicon)
Code:

import mmap

fileid = open('test', "w+")
fileid.truncate(4)

bytes = mmap.mmap(fileid.fileno(), 0)

bytes[0:4] = b'abcd'
bytes[1:3] = bytearray(b'BC')  # CPython passed, while Pypy raises TypeError

print(bytes[0:4])  # CPython prints b'aBCd'

Can confirm: this happens on 3.9 as well.
