want to stop working while uploading to boto3

Question

I'm working on Python 3.9, but I'm writing a program on tkinter and boto3. It's a program for uploading simple files, but the problem is that I want to make a stop button when sending. I tried to kill the thread, but An error occurs.

this is the button

 self.thread_file = threading.Thread(target=self.defsend)
        self.send_file = tk.Button(app,
                                   text="send file(s)",
                                   command=self.thread_file.start)
        self.send_file.place(x=635, y=380)
        self.thread_point = 0

this is the send function.

def defsend(self):
    self.thread_point = 1
    
    self.send_file.config(text='Stop')
    
    filename = (self.file_list_box.get(0, tk.END))
    self.item_qty = self.file_list_box.size()
    self.item_run_qty = 0
    try:
        for filename_index in filename:
            self.filename_index = filename_index
            # ?? ??
            config = TransferConfig(multipart_threshold=1024 * 25, max_concurrency=10,
                                    multipart_chunksize=1024 * 25, use_threads=True)
            bucket_name = '4by4inc-eu'
            # ?? ?? ??? / s3??? ?? ?? ??
            self.sendfilename = filename_index.rsplit('/', 1)
            bucket_file = (self.aws_name + '/' + self.sendfilename[1])

            
            self.item_run_qty = self.item_run_qty + 1

            #?? ??? ?????.
            test_1 = "Sending ..." + self.sendfilename[1]
            self.log_list.insert(tk.END, test_1)
            self.log_list.see("end")
            self.percentage_1 = 0

            ###################################Here boto3!!!
            #################################################
            self.s3.upload_file(str(filename_index), str(bucket_name),
                                str(bucket_file), Config=config,
                                Callback=self.test_def)
            #self.s3.upload_file(filename_index, bucket_name, bucket_file, Config=config, Callback=ProgressPercentage(filename_index)) 

            test_1 = "( " + self.sendfilename[1] + " ) transfer complete."
            self.log_list.insert(tk.END, test_1)
            self.log_list.see("end")


        paginator = self.s3.get_paginator('list_objects_v2')
        response_iterator = paginator.paginate(
            Bucket=self.bucket_name,
            Prefix=self.aws_name
        )
        self.progressbar_label.config(text="Done")

        self.file_list_box.delete(0, tk.END)
        self.s3_list_box.delete(0, tk.END)

     
        for page in response_iterator:
            for content in page['Contents']:
                self.s3_list_box.insert(tk.END, content['Key'])
        self.send_file.config(state=tk.NORMAL, text='send file(s)')
    except :
        self.send_file.config(state=tk.NORMAL, text='send file(s)')
        messagebox.showinfo("error", "Click the login button")

and this is progressbar

    def test_def(self, bytes_amount):
         #print("in")
         #print(self.filename_index)
         _size = float(os.path.getsize(self.filename_index))
        _lock = threading.Lock()
        _seen_so_far = 0
        with _lock:
            _seen_so_far += bytes_amount
            percentage = (_seen_so_far / _size) * 100
            #sys.stdout.write(
            #    "
%s  %s / %s  (%.2f%%)" % (
            #        self.filename_index, _seen_so_far, _size,
            #        percentage))
            #sys.stdout.flush()
            self.progressbar.step(percentage)
        self.percentage_1 = self.percentage_1 + percentage
        _on = int(self.percentage_1)
        str(_on)
    
         self.progressbar_label.config(text=str(_on)+"% "+"( " + str(self.item_run_qty) + "/" + str(self.item_qty) + " )")

I tried

"self.thread_file.daemon = True "

but I got an error.

Error: thread wasn't killed

What shoud i do?
