Purchasing packs from emporium

When ever i try to buy a pack on pc it stops i can’t move anywhere it stops working

Same thing is happening to me.

I tried everything to no avail.

Had the same problem but figured out how to fix it. You need to craft an item that uses astral gems (can’t remember which one but it’s a killer item) until you deplete most of your gems. After that start earning astral gems again and it will start working.
