Spyder: Can't launch Spyder on Windows 10

[alexkopytin]

Description of your problem

What steps will reproduce the problem?

I typically open Spyder via the Start Menu, but now, when I try to click on the Spyder icon in the Start Menu, I get no response. I then tried to go directly to the spyder.exe file in the Scripts folder in the directory where Anaconda is installed but I got no response.

Please provide any additional information below

Versions and main components

• Spyder Version: 3.2.4
• Python Version: 3.6.2
• Qt Version: 5.6.2
• PyQt Version: 5.6.0
• Operating system: Windows 10

spyder --reset
solves the problem

I am having a similar problem. When I attempt to run Spyder, I get a pop-up saying that Python has stopped working. I have tried launching from start menu, navigator, and prompt, but I get the same result each time.

I am running Anaconda Navigator 1.8.7, with Spyder 3.2.8, and I have Python 3.6 installed on the machine.

Most probably it's an antivirus original firewall problem. Please deactivate them an try again.

[Belay7]

I deactivated both and still had the same problem. I tried restarting with both still deactivated, and still had the same issue. Spyder will not start when trying to open from start menu or Anaconda Navigator, and I am still getting the message that python has stopped working when I try launching from prompt.

same problem here.. spyder window is showing loading editorand it never open nor get cloosed. i hav eto close it manualy

[MChetanSR]

I too have the same issue. It is stuck at the "loading editor..." phase. Nor could I launch jupyter notebook. When I run jupyter.exe or jupter-troubleshoot.exe, a window opens and closes in a fraction of second. I had this problem a month ago. So I switched to Ubuntu. It seems its working fine in Linux.

No, i can ooen julytrr and work on that but spyder is not working. I have
tried almost all possible way to solve it but nothing worked.

This works for me: In windows 10 (run this in conda prompt, might need to run as admin)

conda install --force-reinstall pyqt qt

see here:

try this:

conda install --force-reinstall pyqt qt

spyder --reset
solves the problem

The above, after reinstalling pyqt (quoted below) solves the problem for me.

try this:

conda install --force-reinstall pyqt qt

I had the following error message, when trying to launch Spyder from my conda environment (in other words the environment was already activated and running)

This Python interpreter is in a conda environment, but the environment hasnot been activated. Libraries may fail to load. To activate this environmentplease see https://conda.io/activation

The above Spyder --reset did the trick for me (I have also used 'update qt' though before that as suggested on one of the stackoverflow answers... just before that, so maybe try both)

I have Windows 10 and Spyder wont even launch for the first time immediately after installing the most recent version of Anaconda. Anyone else having this issue recently? (November 2020)

[foobar77]

I have Windows 7 and Spyder wont even launch for the first time immediately after installing the most recent version of Anaconda. Next I tried installing Winpython64-3.8.6.0 in order to launch spyder from there. No luck there too.
