How to activate anaconda environments properly after installing visual studio 2019

Question

After installing Visual Studio 2019, I have problems with my anaconda. When I create a new environemnt in my anaconda, after hours I face the problem when I try to activate the environment and after that when I open any jupyter notebook, the kernel will not work. I copied the messages when I activate environment. How can I recover my anaconda environments? I have uninstalled the Visual Studio and deleted all its files but the problem is still here. I appreciate any help to solve this issue. I am using Windows 10 and Anaconda 3.

It was solved by removeing the vs2017_compiler_vars file that was in Anaconda3\envs\enviro\etc\conda\activate.d .
