Hi @XareXD ,
Welcome to Microsoft Q&A!
Which version of Visual Studio are you using? What are your project type and target framework?
Please close all running VS instances and open the Visual Studio installer > Modify > Individual components tab > ensure that the .NET SDK is installed.
You can remove all package references and add them again using NuGet Package Manager.
Or create a new project and check if it occurs in specific projects or not.
If it doesn’t work, please share us more detailed information to investigate it further.
Sincerely,
Anna
