I am not a lawyer specialized in Armenian migration laws, but it seems you will be forced to pay a huge fine.
առաջացնում է տուգանքի նշանակում` նվազագույն աշխատավարձի 100-ապատիկից մինչև 150-ապատիկի չափով:
a fine equal to 100-fold to 150-fold of the minimum salary.
The minimum salary seems to be 55000 AMD.
What will most likely happen on a border crossing checkpoint is you will be detained and debt enforcement authority will be asked to cease the debt from you.
What you should really do is find a lawyer (perhaps some free law clinic?) and not rely on bits of advice from random people on the Internet.
