python – Error when I open Spyder: pylsp >=1.7.2,

I upgrade conda and spyder right now, but I have and issue.

I used:

[1]conda update anaconda
[2]conda install spyder=5.4.3

I also used:

pip install pylsp-mypy

I used [1] in the spyder terminal first and then I used it in the conda prompt, I don’t know if that caused the error.

How can I solved it?

Edit (temporal solution):

Now I used conda install --revision 0 , and this fresh Anaconda installation, with the drawback of needing to install every package again. Hovewer, all environments created remain intact.

I don’t know what happend, but when I write [1] and [2] in the prompt again and I got the same error. I don’t know if is a version issue. If someone have a solution about this problem, I would like to read it and understand and understand why the problem happened.
