Could you also share your settings.json?

[djsavvy]

Sure. Do I need to scrub any personal information (i.e. GUIDs?)?

[zadjii-msft]

Nah, GUIDs are basically just random numbers

You seem to have closeOnExit set to always. Can you comment that out?

It’s possible that your default profile is exiting before it displays anything, which can look like a crash. If this is the case, we’ll need to go figure out why it’s exiting so fast.

[DHowett]

(This is why we switched the default closeOnExit setting to “if the process didn’t fail”)

[djsavvy]

Thanks for the suggestion! However, commenting out the closeOnExit line had no effect --- still exiting/crashing on startup.

[DHowett]

Thanks!

[DHowett]

Okay, this is a shot in the dark. Can you change your fontWeight from regular to medium? I can't reproduce a crash with that value, but it _does_ cause a settings load failure that might be implicated in a startup crash. :smile:

[djsavvy]

Wow! That fixed it! Also, if I change the fontWeight back to regular after opening Windows Terminal Preview then it crashes.

Thanks so much for helping me debug --- I don't think crashing is the right behavior here, but I never would have guessed to look there. Thanks again.

[DHowett]

That's the weirdest part: this is what I get with the same version of Terminal (!)

Thanks for helping troubleshoot with us!

[DHowett]

_oh no, the behavior changes on the insider build of windows_

[djsavvy]

Oh boy. Good luck debugging that! (and if possible, keep me posted --- I'm so curious what could possibly cause something like this)

[DHowett]

So, to keep you in the loop!

The Windows Insider builds support hardware-enforced stack protection, and there was some work done in the compiler/linker shipped with Visual Studio 2019 16.7 to support laying down exception handling metadata.

It looks like there's a disagreement about what that metadata should look like between Windows and the compiled binary. :smile:

Still figuring out whether it's a Windows bug or a compiler/linker issue!

[omardelrio]

Experienced the same issue apparently - the new version crashes on startup.

I am on Windows build 20201.
Windows Terminal 1.3.2382.0

This is on my event log:

Faulting application name: WindowsTerminal.exe, version: 1.3.2008.25002, time stamp: 0x5f45907e
Faulting module name: ntdll.dll, version: 10.0.20201.1000, time stamp: 0x88c00ec6
Exception code: 0xc0000005

In my case, removing "antialiasingMode": "clearType" fixes it, these are my relevant settings:
