matplotlib, cv2, pillow etc. windows all close immediately EXCEPT the first time after restarting windows

matplotlib.pyplot.show(), Pillow.Image.open(), cv2.imshow() all open the correct image/plot and then close almost immediately.
But they all work the first time after I restart WINDOWS. Restarting the Ubuntu shell doesn't help.
I'm using VSCode, WSL2, Ubuntu 20.04, I've tried a few different versions of Python with Pip and Conda

How do I get Spyder to launch after Catalina update with fresh anaconda install?

I've been using Anaconda spyder (Python 3.7) on MacOS Catalina for about the past 3-4 weeks for a project I have been working on. However, I have noticed that after clicking launch on the navigator that Spyder won't launch. I have tried a clean install of anaconda using both pkg installer and command line installer. To uninstall I use anaconda-clean.
If anyone has ran into this issue and has found a solution please let me know. I would also accept a similar development environment that has a good object inspector like Spyder.

How can stop running two Python3 Versions on Jupyter Notebook?

After reset my Mac, I installed Anaconda3 and add Python2 environment to Jupyter Notebook. Then I have this problem when I click the tap. enter image description here
Always two same functions appears. Therefore, I guess Jupyter Notebook is working on two Python3s. How can I solve this? Anybody had the same problem?
Environment: macOS High Sierra
Python3 3.6.4 installed from Anaconda.
Python2 2.7.15 already installed from macOS (I guess).
Anaconda 4.4.10
Jupyter 5.4.0
Thanks in advance

Anaconda Installation: ungtz.dll error

I tried to install Anaconda using the normal python 3.5 windows 64-bit .exe file. Every time I run the installation, all the extraction in it fails due to error of some ungtz.dll file as shown in the picture. Even my Antivirus detects that file as a Trojan and repairs it.So after the installation ends there is not Anaconda Prompt and other such software.

Python crashes when trying to start Anaconda navigator

I just installed the Anaconda package (64 bit, python 2.7) on my Windows 10.
Python itself works fine. The programmed code gets executed fine.
However, when I try to run the Anaconda Navigator or try to run conda command in the windows prompt python crashes.
A windows error pops up, telling me "Python has stopped working".
Does anyone have an idea how I can fix this? I tried to reinstall the Anaconda package, but it didn't work.
Generally uninstalling Anaconda might break the newer installations.
Try this, it help me solve similar issues with missing Anaconda Navigator and broken anaconda installations after an uninstallation.
Hope it helps you. :)
EDIT
The version of new packages should be the same with the base Miniconda.
For Python2 do conda install anaconda=5.3.1=py27_0 anaconda-navigator=1.9.6=py27_0.
The important thing to specify the Python 2.7 build.
You can search more information about packages with the conda show <package> command for versions and builds.
