ImportError: DLL load failed: %1 is not a valid Win32 application - kernel error at jupyter notebook

I am experiencing the following kernel error at jupyter notebook. This problem has started after having installed new version of python(3.8.2) and visual studio python package. I have tried to uninstall and reinstall anaconda but it isn't still working.

 Traceback (most recent call last):
