None.
But I will google it.

Answer 1

The issue solved.
The first try:
After I reset the Spyder with the command in Anaconda Prompt.
spyder --reset
then restarted Anaconda Navigator.
The issue is NOT solved.
The second try:
After that, I read the error messages carefully.
I found that there is and indentation error in
C:\Users\user\anaconda3\lib\site-packages\spyder_kernels\py3compat.py, line 356 c exec(code, globals, locals) ^ IndentationError: expected an indented block
Then I open the
C:\Users\user\anaconda3\lib\site-packages\spyder_kernels\py3compat.py"
with VSC (Visual Studio Code)
Then modify the line in the file.
c exec(code, globals, locals)
to
exec(code, globals, locals)
Save it and restart Anaconda Navigator.
Then the issue is solved.
I think the reason is that, with no purpose, I modify the line
exec(code, globals, locals)
to
c exec(code, globals, locals)
