`dotnet new list` locks up terminals

[dsschnau]

Describe the bug

When I run dotnet new list in a terminal, my console locks up and I can't do anything but open a new terminal window. dotnet new list isn't the only dotnet command that creates this behavior, but it reliably reproduces it without writing any code.

To Reproduce

• run in cmd dotnet new list
• see list of dotnet templates available
• terminal locks up, no input is read, CTRL-C doesnt' work, etc.

Exceptions (if any)

Further technical details

• Include the output of dotnet --info
• The IDE (VS / VS Code/ VS4Mac) you're running on, and its version

C:\Users\dssch>dotnet --info

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@dsschnau does this reproduce with 8.0.300? If it's hung, are you able to attach a debugger and save a dump to provide for us to investigate?
