Hey @leavor, thanks for reporting. We'll take a look at this in our next version.

For now please run

spyder --reset

and don't create projects in directories that contain non-latin characters.

leavor · 2021-04-19T02:27:23Z

After use the "spyder --reset" in Anaconda,Spyder can start, but there is another problem.
First, I opened an existing project named "Algorithm", and failed. The bug report is the same as above.
Then, I created a new folder named "aaa" as a project folder, which also failed.

Finally, I opened the existing new project "aaa" , succeeded

Please close Spyder, open the Anaconda prompt and run there

conda install jupyter_client=6.1.12

That should solve your problem.

ccordoba12 · 2021-04-22T17:12:53Z

I found the second you reported above (i.e. the one with the very long error traceback) is a duplicate of issue #15356. We'll fix it in our next release.

leavor · 2021-09-29T06:48:38Z

Hi, @ccordoba12 , I have fixed this bug.

I changed the code in this file, "python\Lib\site-packages\spyder\plugins\projects\plugin.py"
However, I am not sure about the impact of this on spyder's entire project.

ccordoba12 · 2021-09-30T01:34:49Z

Hi, @ccordoba12 , I have fixed this bug.

Hey @leavor, that's really good to hear!
