@fssfs at least in EU version of the game with some end game save from gamefaqs I had no problem casting that spell on 1.2.2 version which Open Emu seems to be using.
Probably best if you report that issue to Open Emu project devs as they should know better what changes they're doing to make ppsspp work in their project which could affect emulation.
Or maybe you're also just using some corrupted installData as the person above, as far as I tested in my version install data works fine, through that's an useless feature when you're not playing from physical UMD only few games use it to unlock stuff and this is not one of them.
