Hello, first thanks for your awesome GUI implementation!
I have used this boot picker since OpenCore 0.5.6 to 0.5.8 and it worked well, but the boot picker seems to be no longer to work on OpenCore 0.5.9. I'm wondering if there is something wrong I have done, but I may confirm that nothing I did except updating the OpenCore. Does current release of NdkBootPicker supports OpenCore 0.5.9? I would be grateful if you can investigate about it.
