Issue Description

I updated my local visual studio from 17.12.4 to 17.13.0. Since then my local build inside visual studio or directly using msbuild is broken. Files with build action None and CopyToOutputDirectory=Always are no longer copied to it's target path. They are simply missing. I was already able to see whats causing all this. It's a simple brace in my path. I made a sample app for this. Take a look at this:

Steps to Reproduce

To reproduce open the Developer Command Prompt for VS 2022 for example and execute the following command inside the cloned repo:
MSBuild.exe ConsoleApp2.sln -t:Build -p:Configuration=Release -v:quiet -m /restore

Check this file for the diagnostic output of that command (in german): diag-log.txt

Expected Behavior

The files should be copied to the output directory.

Actual Behavior

No file is copied to the output directory.

Analysis

As noted above the brace ( in the path is causing this.
