I've been running my code on python idle while working on this and didn't receive any problems until I tried running it on visual studio. When running it the tk window just closes and it doesn't go to the classes it tells it too. I am still learning so I probably have some mistakes I would love to get any feedback.

Hi I've been trying to implement a DHT22 temperature and humidity sensor with Tkinter GUI where it updates regularly while using the GUI. This is done on a Raspberry Pi 4 using Python. However, while the numbers are updating correctly, it would cause the GUI freeze momentarily while updating the numbers. I have already tried multithreading, but it unfortunately didn't help. Is there any solution to this problem? Any help is greatly appreciated.
Here's the code:

I'm not sure if my approach is optimum but this is how I worked it:
I adopted multithreading and created two threads one that is running the Tkinter GUI and the second thread runs the python script.
The python script writes the output of one function to a text file while the GUI on the first thread reads the same text file and triggers the action.

I've 2 questions on your code of changing an image periodically. I've run your code and the images are changing perfectly fine, but when im trying to include your patch with mine the images isn't in order and random images are generating. my code is about web-socket program where the rpi is the client and esp32 is the server and the data is coming in sprintf format.
The thing is that I've to take that data and paste on the images I've in my dir.
there are 4 images and each image has 4 different parameters.
My 2nd question is that when the image is change the data should also get change periodically. also can i set the timings of an image like which image should get display first and its data too.
It'd be a great help if you can enlighten me on this.
i'm putting my code below for your reference.
