The game's RNG doesn't manage its chaos inputs nearly well enough - you would eventually pass the check with determined reloading, but while you're reloading to the low swing of the algorithm (and it seems to return to the same state upon reloads, or at least to being at the same stage), it's going to take far longer than it 'should' under normal expectations.
This is hard to verify in any concrete way, given that probability is exactly that, even with machine rngs, but there is a strong correlation of this phenomena.
Be prepared also for numerous people to chime in on the topic of confirmation bias, and about their various successes with the check you were stuck at - I've passed and failed every check in the game, variously, and none of them are 'rigged', per se, though a couple of them do seem to have an in-built bias, behind the curtain.
