Hi Stephen,

Thank you for the feedback! Indeed, I think an issue has been already created:  Kernel doesn't start - permission denied · Issue #21892 · spyder-ide/spyder (github.com) Sorry for the inconvenience! If you have any further info in order to better understand what could be happening or feedback please post it there!

Best regards,

Daniel

Thanks for the announcement. What Python version does Spyder 5.5.2 run? 

F.

[Daniel Althviz Moré]

If you are running Spyder from the Windows installers currently they use Python 3.8 (3.8.10 to be exact) for the default interpreter. Also, I think when using the macOS installers is Python 3.9. Also, just in case, you can create a Python environment with the Python version you would like to use and set is as a custom interpreter. For more info about that you can check:  Frequently Asked Questions — Spyder 5 documentation (spyder-ide.org) 

Best regards, 

Daniel
