Can't open package manager console in visual studio 2019

I am learning asp .net from this udemy course udemy_course_link. Whenever I open package manager console in visual studio 2019, Following error comes :

The error message is: Unable to cast COM object of type 'System.__ComObject' to interface type 'EnvDTE80.DTE2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{2EE1E9FA-0AFE-4348-A89F-ED9CB45C99CF}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).

I am new to visual studio. I found a similar question in StackOverflow but that didn't help.
