строка 77 равна db.execSQL("ALTER TABLE User ADD COLUMN MAXLEVEL INTEGER DEFAULT 0")

Веселье onUpdate:

override fun onUpgrade(db: SQLiteDatabase, oldVersion: Int, newVersion: Int) {
        db.dropTable("User", true)
        if (3 > oldVersion) {
            db.execSQL("ALTER TABLE User ADD COLUMN MAXLEVEL INTEGER DEFAULT 0")
        }
    }
