Barangkali agan @entebah bisa mencoba menggunakan Electrum portable untuk membuka file wallet yang error tersebut.
aku malah download ulang wallet electrum dari versi 2.9.0 hingga 4.3.3 yang versi portablenya dan anehnya masih error.
aku punya 3 wallet yang seperti ini, padahal pas aku check wallet aku yang lain itu ada yang aku buat dari 2016 dan sampai sekarang masih bisa aku gunakan cuman 3 wallet saja yang ngga bisa kebuka sampai sekarang.
Sesuai saran Husna, Nanti Setelah download versi standalone, buka electrum, lalu bikin wallet baru dulu, setelah selesai dan wallet baru terbuka, lalu pergi pojok kiri atas lalu klik file > lalu pilih new/restore, lalu pilih choose, lalu pilih file wallet yang lama. (ingat ya file wallet bukan yang lain)
Jadi bikin wallet baru hanya untuk memastikan kalau wallet electrumnya running well. Kalau sekiranya berjalan baik, langsung saja choose wallet file di awal.
Sebenarnya dalam file wallet itu ada seed juga. Coba deh buka file wallet lama sampeyan pake notepad atau kalau tidak bisa pakai notepadd++ , ini contoh file wallet punya saya, kalau discroll ke paling bawah akan nemu 12 kata seed. (Ini file wallet saya tanpa password.)

Jadi, kalau nemu file wallet dan seed tersebut, mulai saja dari awal untuk create wallet.
