Yeah may be delay, let us check that, it was working on murata module so same as DISCO_L072CZ_LRWAN1, that's strange your board can't connect

From the tests I did on a custom Murata-based board, if the sleep period is greater or equal to 9ms, the device is unable to receive a join accept.

Thanks @mickael868, this mean that 5ms looks like correct value (no magic, I took this 5ms from code of other stack).
Pay attention to SPI, SPI communication with sx1272 won't work if TCXO is not enabled. Worth mentioning this one
@jeromecoutant could you please confirm it now works with your DISCO_L072CZ_LRWAN1 ?
