Windows Terminal will not open

Windows Terminal version

Windows build number

Win10 22H2 build 19045.4355

Other Software

N/A

Steps to reproduce

Windows Terminal will not open now, as of a couple weeks ago.

It will not run by opening wt.exe, or WIndowsTerminal.exe. Regularly, or as administrator. In it's default folder, or by typing wt.exe in "run:"

I've tried rebooting, I've ensured the system is fully updated, I've tried Settings>Apps>Windows Terminal>Advanced Options> Terminate/Repair/Reset.

It started with v 1.19.11213.0 which I've had installed from Windows Store for a while now. It was working fine up until a couple weeks ago. I don't know what's changed other than maybe a system update? I've also tried uninstalling it then reinstalling it - same issue. Then, I uninstalled it and installed v 1.21.1272.0 - same exact issue. It runs at first launch after install, then won't open after.

It will only open from Windows Store > Windows Terminal > "Open" -- but without any of my settings.

I've looked online (and yes, I've looked in Github Open & Closed issues) and I've tried just about everything except the generic MS Agent response to:

1) del /f /s /q /a "%LocalAppData%\Packages\Microsoft.WindowsTerminal_*\LocalState\settings.json"

2) Download windows installer > Upgrade PC Now > Keep Files

I am not going to reinstall windows and have to backup 1tb of data or risk it being lost over this.

There needs to be a different way?

I'm at the point of deleting anything "WindowsTerminal" in Windows Registry but I have not done so unless you tell me to, or another option.

Windows Resource Protection did not find any integrity violations.

Edit:

Per the github-actions bot, before posting this I also did find #14133 which refers to #14104 - which recommends to simply install "Windows Media Feature Pack" -- however, that is for Windows N versions. So I did not do it.

They also reference #14110 & #14124 - which appears to be a different error, but it did prompt me to look at Event Viewer:

Appears to be a different faulting DLL than those issues referenced.

Per the feedback in all of those issues - I will also send feedback via the Feedback Hub, however I really would appreciate some insight or a fix here asap because Windows Terminal is meta, and I need to use it!!!

Thanks!

Expected Behavior

The program to run regularly.

Actual Behavior

The program will not open other than via Windows Store > Open, with stock settings.

Start by reproducing the launch failure on Windows 10 22H2 with the listed Terminal versions, then review the Event Viewer reports showing ucrtbase.dll and exception 0xc0000409. Compare the referenced issues #14133, #14104, #14110, and #14124 for related failures. Done means identifying a reproducible cause and restoring normal wt.exe launching with the user's settings.
