sudah berhari-hari sejak saya terjebak dengan kesalahan ini. Seperti yang Anda lihat di log, ada Kivy dan Python versi terbaru tetapi saya mendapatkan PermissionError dan NotImplementedError. Saya mencoba menjalankannya sebagai pengguna super tetapi masih tidak berhasil, karena saya tahu itu harus berfungsi tanpanya.
ketika saya menjalankannya sebuah jendela muncul tetapi tidak menampilkan teks sama sekali, hanya ada satu artefak di tengah yang menghilang ketika saya mengklik tombol, semuanya tampak baik-baik saja.
