It says my stasis class : Requires Destiny 2: Beyond Light. So I bought Beyond Light on Steam. But then, when I found out that I cannot get DMT, I did something that I think is normal, which is to return it, and buy the deluxe edition. However, for unknown reason, I cannot change to my stasis class, even though I have beaten the ice queen (forgot the name) and claim the 4 of 4 splinters.
