Just installed Through MS Store, launcher switching to Japanese automatically

As the title states, I just installed PSO2 through the MS store, and the first time it launches, its in English, but then it immediately "Downloaded the latest launcher" and once it restarted I was on the Japanese launcher. Please help.

Bump for visibility

Anyone else facing this?

Fixed it!! (At least for me).

Go to your Documents, Sega, Remove everything here. Relaunch the launcher, enjoy the English!

I think this happened because I tried the install method that didn't need Microsoft Store >.> (Download the Jap Launcher seperatly and try to trick it to do NA)
