Thank you all for your kind reply! I have tried the above methods and it did not solve the problem
In the Windows version of Evernote 10.2.4 1949, the notebook list cannot be displayed normally, but it can still be displayed normally in the web version or the old version, so it should be a bug in this windows version.
Before this happened, there was a issue where Evernote 10 repeatedly displayed the notebooks. After it happened, I moved the note in the notebooks to the new notebook, and then deleted the duplicated old one. Then this situation occurred. This may be a hint.
