Unable to remove LSFG-VK patch from Granblue Fantasy Relink (Unpatch option missing)

[Ayorin]

I applied LSFG-VK to Granblue Fantasy Relink, and when I launched the game the situation I got is the one you can see in the picture.
I tried uninstalling and reinstalling the game but nothing changed. I also removed the plugin, but that didn’t fix it either.

I read online that to disable it I should use the unpatch option, but I can’t see that option in the plugin on Decky anymore.
