Python

Hi , recently I have problem on debugging in spyder 5.1.1. I have checked online and note that they have some issue on debugging in spyder version 5. I have also tried to install spyder 5.2.2 but still not able to debug so I decided the downgrade to Spyder 4. However, it not working either , so I tired to uninstall Spyder and reinstall spyder 2.4.2 in anaconda. after installed , I cannot open spyder and I got the following message from a pop up window when I tried to launch spyder in Anaconda:

Application spyder launch may have produced errors:

Any advise on what should I do so that I could open the Spyder again? Much appreciate

What I have tried:

I have the same questions on github but still have further problem on that after getting the advice from other experts. (https://github.com/spyder-ide/spyder/issues/17920#issue-1239365635) What should I do so that I could run the Spyder properly again?
