Hi Brian Poole,
Thanks for posting here.
Since this forum is to discuss the MSBuild (Topics including: usage of MSBuild, build customization, and MSBuild extensibility via tasks, loggers and hosting), it is hard for us to make sure that whether it is related to the Windows, the project
itself or others, I have no direct solution for this issue, but I could provide you a troubleshoot for this issue.
Create a new application or create a new account with administrator permission, check if the new application and new account still has this issue? If you still have this issue, this issue seems more related to the windows update, you can open a new thread
on the windows forum or you can try to roll back your system to the previous version. If that issue not occur on the new app or account, this issue should be more related to your project, you can try to copy the
scripts to the new application.
Hope this helps.
