Hello @ESTEBAN UGALDE,
Welcome to Microsoft Q&A forum.
Please try to/make sure that following workload and components have been installed:
Workload
=> ASP.NET and web development
Components
=> .NET Framework project and item templates
=> Additional project templates (previous versions)
=> .NET Framework 4.8.1 development tools
Maybe this issue is caused by .NET Framework. I would suggest you also download and install .NET Framework 4.8/4.8.1 SDK from here: Download .NET Framework. If you have installed it, try to repair it by running the setup file of .NET Framework 4.8/4.8.1 => Repair.
Besides, there's a similar issue here: Unable to make a Web Form Project with a template. If this error persists, kindly follow, add comments on that ticket and wait for any latest update.
Sincerely,
Tianyu
