python3 running over 120.9% of CPU (screenshot)

I don't know why all of a sudden python3 decided to run over 120.9% of CPU but I'm facing this problem since last week and I still couldn't find out the solution.

I don't know why I can't find any application that is written in Python and that requires this much of CPU usage, as you can see clearly in that screenshot that only python3 interpreter is using way too much of CPU.

I can't delete python3, if I do so I will crash my system, please post a solution to this problem.

I tried to find out the application that python3's interpreter was running using the solution given by WinEunuuchs2Unix and found out that it was Visual Studio Code jedi language server that was using this much of CPU.

Now help me to find out how to disable jedi language server support on Visual Studio Code (if there is nothing you can do with the CPU usage).

The solution to this problem as suggested by a user Iuabud at Rouge Python Processes with High CPU ...

Note: The steps I'm mentioning are only applicable if python's run-jedi-language-server.py is consuming a lot of CPU in your system.

Open the command palette (View > Command Palette...) or Ctrl + Shift + P.

Run the "Preferences: Open Settings (JSON)" command. This will open the user
settings in VS code. You don't want to open defaultSettings.json open
setting.json.

Paste the following line in the settings file:
"python.experiments.optOutFrom": ["pythonJediLSP"] and save the file.

Reload the window (either by closing VS Code and opening it again or running
the "Developer: Reload Window" command from the command palette),

Ctrl + Shift + P and write the command Reload Window

Edit: It's been two days since I'm no more struggling with this problem so what I think is this is the solution of the problem.

Update

Microsoft has released new language server for python called Pylance, if you had to disable jedi-language-server I would recommend going for Pylance as a language server for Python, here is a link to Pylance documentation pylance-release go and check that out.
