It's not obvious to me what may be causing this error. It may be a simple timeout but this started to fail suddenly on 08/02

runtime/src/libraries/System.Diagnostics.Process/tests/ProcessStartInfoTests.Windows.cs

Line 118 in 10d9e72

Assert.True(p.WaitForExit(WaitInMS));

And it only happens with ProcessWindowStyle.Minimized and UseShellExecute=true.
