The "CreateAppHost" task failed unexpectedly when building a project that is streamed from Google Drive for Desktop

[CanePlayz]

Describe the bug

Building any project that is streamed from Google Drive with their desktop app fails. Building on any .NET 7 SDK on the same device with the same setup works flawlessly. Building on the .NET 8 SDK with files not streamed from Google Drive also works fine.

To Reproduce

Stream (not mirror) files of a dotnet project with Google Drive to your PC, then try to do dotnet build or something similar which involves CreateAppHost. Even if you stop sync, it will not work. First, it'd be great if someone could reproduce that setup and see if they also encounter this problem.

@vitek-karas @elinor-fung since the exception is in the host apis.

Confirmed - I also encountered the same issue with a project in streamed Google Drive directory.

[AldworthClass]

I also have this same issue. We updated the version of VS2022 and this error crept up. It doesn't seem to apply to old dotnet Framework applications though.

I hope it gets fixed.

I can also add some more information to this bug:
All of my computers using Visual Studio (17.3.3), run/stream programs from Google Drive using the Google Drive app. This has been no problem for several years.

My computers that have Visual Studio Community 17.3.3 work fine, and do not get this error. We updated VS on some of the computers to 17.8 and above, and those ones are experiencing this error. I'm not sure exactly which update brought about this error.

[KyleLusk]

I have this same issue with Visual Studio version 17.9.5. Started happening after I updated my project to the latest .NET version. Previously was using .NET framework 4.6.1.
