Getting error with OSError: [WinError 87] The parameter is incorrect:

Question

I want to make a script (GUI) in which I have to convert my text to a png file with the handwriting but I still get this error

I try with "\\" instead of "\" at path

I want to change its name every time I make a new file, because it replaces the old file with a new one

   File "C:\Users\790\OneDrive\Desktop\scrisdemana\main.py", line 16, in click
os.rename(r'C:\\Users\\790\\OneDrive\Desktop\\handwriting\\here.png',r'C:\\Users\790\\OneDrive\Desktop\\handwriting\\handwriting_' + str(x) + '.png')
OSError: [WinError 87] The parameter is incorrect: 'C:\\\\Users\\\\790\\\\OneDrive\\Desktop\\\\handwriting\\\\here.png' -> 'C:\\\\Users\\790\\\\OneDrive\\Desktop\\\\handwriting\\\\handwriting_2021-06-20 13:20:22.660063.png' 

this is my code:

from tkinter import *
import pywhatkit as pwt 
import os
import time
import datetime

#pwt.text_to_handwriting("text","C:\\Users\\790\\OneDrive\\Desktop\\scrisdemana\\here.png", [10, 10, 10])

def click():
    x = datetime.datetime.now()
    entered_text = textentry.get()#this will collect the text from the text entry box
    output.delete(0.0, END)
    definition = pwt.text_to_handwriting(entered_text,"C:\\Users\\790\OneDrive\\Desktop\\handwriting\\here.png", [10, 10, 10])
    os.rename(r'C:\Users\790\OneDrive\Desktop\handwriting\here.png',r'C:\Users\790\OneDrive\Desktop\handwriting\handwriting_' + str(x) + '.png')
    output.insert(END, definition.text)
