Environment

Windows build number: 10.0.20226.0
Windows Terminal version (if applicable): 1.4.3243.0

Any other software? **please tell me how to gather that info and I'll send it to you**

Steps to reproduce

I've just noticed this today. Whenever I start terminal (either by gui or wt command line - admin or not) Terminal shows an icon in the taskbar but then crashes without showing window. I was able to use windows terminal earlier this week with no problem. The issue happened on the version v1.3.2651.0, which is where I noticed the error. I did an upgrade to the current version to ensure I had the latest binaries.

Expected behavior

Windows Terminal should start normally

Actual behavior

Terminal shows an icon in the taskbar but then crashes without showing window.
