Arduino IDE cannot find the header file of the librarys

Development Tools IDE 2.x

I am using Arduino IDE 2.3.3. For any library I included from library manager or mannually added by zip, it always output no such file or directory.
For example shown in the image, I installed the liquid crystal i2c library and tried to verify the example, but it said

 #include <LiquidCrystal_I2C.h>
          ^~~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1

Compilation error: LiquidCrystal_I2C.h: No such file or directory

I've uninstall and re-install Arduino IDE for multiple times, but it didn't work.

Any chance that you have non-ascii characters in the path to the library?

Oh, thank you so much. The default directory is in Documents while it is also named "文件." And after I change the directory, it works!
