Microsoft store. Nothing happens after selecting which drive to install PSO2 at.

I am from SEA and I tried switching my region to US and Canada. I got my installation button blue but I cant get pass after selecting which drive to be installed to. I have my system requirement, instead of update, i got more info and cant defect my version of directx, windows and memory. I checked my computer. I have direct x 12, windows 10 18362.778, ver 1903 and 16 memory ram and video ram of 2.9k. What is the issue that i cant get pass after selecting my installation to which drive. nothing appears when i clicked my drive.Screenshot (579).png
