Restore during build with beta 8 on macOS is not stable

I don't know how to collect diagnostics for this yet, so bear with me :)

I observed this in two repos, but I'll link the one I maintain since I can make changes to it directly: https://github.com/fslaborg/xplot

Running the following will cause a system exception on my mac (latest macOS):

dotnet tool restore
dotnet paket restore
dotnet build

The first two succeed, but the second one fails and I get the dreaded system dialog on macOS saying dotnet has crashed. The only log that I get is this:

Microsoft (R) Build Engine version 16.8.3+39993bd9d for .NET
Copyright (C) Microsoft Corporation. All rights reserved.

  Paket version 6.0.0-beta8
  The last restore is still up to date. Nothing left to do.
  Total time taken: 0 milliseconds
  Paket version 6.0.0-beta8
  Starting restore process.
  Total time taken: 5 milliseconds
/usr/local/share/dotnet/sdk/5.0.103/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.targets(195,5): error NETSDK1004: Assets file '/Users/phillip/repos/XPlot/src/XPlot.GoogleCharts/obj/project.assets.json' not found. Run a NuGet package restore to generate this file. [/Users/phillip/repos/XPlot/src/XPlot.GoogleCharts/XPlot.GoogleCharts.fsproj]

There is one project in the repo that does not use paket, and it builds.

If I run the following (note that I shouldn't need to run install I think, since I have already installed dependencies):

dotnet paket install
dotnet build

Then I get the following large error:

But then if I run dotnet build again, it succeeds!

This dance between catastrophic errors and everything working fine seems to happen with some degree of frequency.

Reproduce this in the linked xplot repository with dotnet tool restore, dotnet paket restore, and dotnet build, then compare the failing and succeeding runs. Inspect src/XPlot.GoogleCharts/XPlot.GoogleCharts.fsproj, the missing obj/project.assets.json path, and the reported MSBuild node-launch errors; done means the Paket restore and build complete reliably without the macOS crash or intermittent failure.
