Python LSP not working

[Derek Hohls]

Hi

I have done multiple reinstalls on my Linux Mint machine. Spyder 6.1.1 is running from its own conda virtual environment. I have done a settings reset and, it seems, Spyder is now starting up in pure default mode.

Despite this, code folding, completion and outlining does not work, and the bottom panel flags that the Python Language Server needs a restart. Again, it does not matter how many times I do this, the warning is still there.

When I start in debug mode, the logs show this:

But still no change to the IDE.

I'd appreciate any help to get this to work - have been using Spyder too many years to abandon it now!

Thanks
