Problems on installing Python Package

I plan to transfer my Anaconda from disk D to disk C, so I uninstalled Anaconda from my computer and then reinstalled it to disk C. However, during the uninstallation process, I forcibly cut off the uninstallation process, resulting in the inability to download the Python package after reinstalling Anaconda, and the command line window of anaconda.exe keeps popping up after opening the Anaconda program.
My computer system is Windows 10. When I use Pycharm, I find that I can’t download the Python package, but it can run normally after changing Anaconda to Python3.9. How to solve it? Please help!
