It happens every time ?
Did you upgrade from previous version of studio ? Or is clean install ?
What feeds do you use in nuget ?

Please send us more details.

Those error happens only first time on my PC which upgrade from version 18.2. I just download and install without removing version 18.2.

Were you trying to create a new project or open an already existent one?

i’m try to create new process

But this happen only one time for the very first time after finish installation.
