PyCharm failing with error: “This application failed to start because it could not find or load the Qt platform plugin "windows" in ""”

I've installed the latest version of PyCharm 64-bit for Windows 10 and am running an analysis in it. After running, it is showing an error like this:

"This application failed to start because it could not find or load the Qt platform plugin "windows" in "".

Reinstalling the application may fix this problem.

Process finished with exit code -1073740791 (0xC0000409)"

I've reinstalled it and applied conda update --all, but the problem persists.

Can anyone suggest how to resolve the problem?
