Great thank you for providing me that information, now let’s try this, the problem may be caused by errors in the Spyder setting and configuration files, we can try to fix it with these instructions:

  1. Close and relaunch Spyder and see if the problem remains.

  2. On the menu, select Start, then select Reset Spyder Settings and see if the problem remains.

  3. Close Spyder and relaunch it from the Anaconda Prompt:

  4. From the Start menu, open the Anaconda Prompt.

  5. At the Anaconda Prompt, enter Spyder.

  6. See if the problem remains.

  7. Delete the directory .spyder2 and then repeat the previous steps from Step 1. Depending on your version of Windows, .spyder2 may be in C:\Documents and Settings\Your_User_Name or in C:\Users\Your_User_Name.

Note
Replace Your_User_Name, with your Windows user name as it appears in the Documents and Settings folder.

Please let us know if that fixed your problem and if you need further assistance we are here to help.

Hi Carlos,
I go the very same problem and following the seven steps above don’t help (btw the .spyder2-folder is named .spyder-py3 on my laptop.)
When I try to start Spyder from the anaconda menu it opens a terminal window and also the Spyder splash screen opens, telling me that it is loading all kinds of resources. Then everything closes and I get the lengthy error message Yangje was posting.
The same happens when I try to start Spyder from the Windows Start-Menu.
Any idea? Please let me know in case you need more information.
Thank you,
Markus

Hello,

I am also facing the same problem. However, the error message is slightly different. Here follows the error message (the last line mentions access permisions to windows font).

Is there any suggestion to solve that? I tried what Carlos proposed but no success yet :(.

Hi Charles,
I’m not really sure whether your issue is the same as mine, but I eventually could resolve the issue by following the installation steps from Installation Guide — Spyder 5 documentation. When you scroll down to the section “Conda based distributions” there is a description how to create a new environment with an up-to-date Spyder version. That solved the issue for me. When you start Anaconda, you need to open Spyder from that new environment.
Hope that helps.

Best regards,
Markus

I had the same. Background: I have a Python 3.12 installation AND i want python 3.7 in a different environment.
What didnt work with the result that Spyder wont launch from Anaconda navigator or Anaconda prompt:
I reïnstalled Anaconda and had the recommended checkbox checked with something like Python 3.12 as default.
After the fresh install I created with Anaconda Prompt a new py37 environment with the extension python=3.7.0
then Conda install spyder.
After installation I try to launch Spyder which didnt work.

Now what does work:
I uninstalled Anaconda. I reïnstalled Anaconda again with the third checkbox about python 3.12 as default, ticked off.
Then I installed my new environment for Python 3.7 again, but now with the extension python=3.7. So without the .0 at the end.
After completion I installed spyder with the command: conda install spyder.
After installation I started Spyder, Now it did launch!

So maybe its the checkbox at installation start of Anaconda. Or it is the last .0, or both.

Good luck!
