I'm having a similar issue, since a couple of weeks ago, my dev version has been crashing when opening. I have the Ubuntu WSL, using zsh and oh-my-zsh with the amuse theme as the default.
Today I had time to look into it and saw that removing the emoji ⌚ from my prompt fixed the issue.
I think is a regression, as before this didn't happen and using the Windows Store version: Windows Terminal (Preview) Version: 0.4.2382.0 with the same config works fine. My initial font has been Hasklug NF, but I've tried Hasklig, Source Code Pro and Consolas.

If this is a somewhat separate issue, please let me know so I open a new one.

Or perhaps /dup #2066.

Hi! We've identified this issue as a duplicate of another one that already exists on this Issue Tracker. This specific instance is being closed in favor of tracking the concern over on the referenced thread. Thanks for your report!

[DHowett-MSFT]

I'm concerned that dwm is exiting too. We're not going to be able to keep running when the desktop window manager goes away, and other applications that require composition won't either. We can try to be more resilient here.

[JeremyTBradshaw]

You guys do well to keep on top of these 💪 so well, good job.

Hello there, as an FYI I've recently switched from Edge Insider Canary to Edge Insider Beta. With the switch I've noticed another issue rarely occurs, and this issue (the one I'm commenting in) seems to be on the same schedule. The problem is that the Edge Canary windows would be black/blank. This seems to happen in parallel with the problem here, so maybe it is Edge Canary that was crashing dwn.exe, which then causes Windows Terminal to fail since it needs dwn.

Not sure if this helps to set a direction for the resolution, but figured I'd add this.

This issue has been marked as duplicate and has not had any activity for 1 day. It will be closed for housekeeping purposes.

[DHowett-MSFT]

The bot was overzealous in closing this because I forgot to remove the resolution tag. Sorry!

Just wanted to share that while my issue with Edge Beta windows going all black at the same time dwm faults - has nearly gone away. But the Windows terminal crashing with dwm while the screen is locked is still happening. So my earlier thought that Edge'mium but somehow the catalyst is now overturned and I don't think that's the case.

For anyone else suffering from this issue: I noticed that when I'm connected to my machine via remote desktop and I lock the computer, the terminal crashes when I unlock. But if I'm connected directly to the machine without RDP and I lock the computer, the terminal stays alive. I'm guessing the behavior of dwm differs between these scenarios, and discovering this helped me at least work around the issue somewhat.

[zadjii-msft]

(note to future self: the repro is taskkill /f /im dwm.exe. That will send dwm home in a box, which will take us to the farm upstate)
