While debugging "Duplicate 'PackageDownload' items found." MSBuild throws "Unhandled Exception: Microsoft.Build.Framework.InternalErrorException"

Issue Description

When attempting to msbuild /t:SlnGen dirs.proj for my repo I’m getting an error about duplicate PackageDownload items that look like they’re the .Net Core SDK packages? I’m trying to get more info and used the /pp:out.xml switch. When that didn’t help, I figured I would get the diagnostic verbosity logs. That’s when I ran the command below and MSBuild crashed.

I don't think the problem I'm trying to debug is related to getting MSBuild to crash when asking for diagnostic output but I want to be complete so I'm including it:
C:\Users\joraki\OneBranch\$repoName\src\tools\DeploymentDatasetGenerator\DeploymentDatasetGenerator.csproj: error NU1505: Duplicate 'PackageDownload' items found. Remove the duplicate items or use the Update functionality to ensure a consistent restore behavior. The duplicate 'PackageDownload' items are: Microsoft.WindowsDesktop.App.Runtime.win-x64 [3.1.26], Microsoft.WindowsDesktop.App.Runtime.win-x64 [3.1.26], Microsoft.WindowsDesktop.App.Runtime.win-x64 [3.1.26].

Actual Behavior

Short stack trace

Some command line switches were read from the auto-response file "MSBuild.rsp". To disable this file, use the "-noAutoResponse" switch.

I believe this will be fixed in the next .NET SDK preview (which will ship with the next VS preview). There are some workarounds at dotnet/sdk#24747 (comment).
