After installing Powershell 7.0.2, there is no longer an app icon in the Taskbar. Instead, there is a white rectangle, the standard placeholder icon. This is confirmed on two Windows 10 Pro machines. Screenshot below, followed by environment data.

Screenshot. See the white rectangle next to the VS Code icon in the center. That's Powershell 7.0.2:
