If you have that access to this platform before you went ahead making deposit why didn't you consult people around here to know if they had also used this gambling site and how was their experience with the gambling, at least this could have saved you stress over that site
If you are active in this section, like i am, you'd understand that even the most "popular" crypto casinos still get their own fair share of scam accusations. So, using them doesn't mean you'd not fall into situations like this one.
Don't get me wrong though, i am not endorsing new or unproven casinos, not at all. I would recommend popular casinos, not because they cannot block your withdrawals, but because they have a reputation to protect, so they would be more responsive to dispute resolutions than newer casinos.
