Fixed this by repairing it via Add or remove programs.

So it turns out Windows automatically syncs the profiles.json between different computers under your MS account. And it seems that if the synced profiles.json includes something that is not suitable for the host, e.g., a font not installed, the Windows Terminal crashes without giving any warnings or logs.

For my case, I manually entered the directory %LOCALAPPDATA%\Packages\Microsoft.WindowsTerminal_8wekyb3d8bbwe\RoamingState and deleted the synced profiles.json from my laptop, which does exist but for some reason was not found in everything. The file included a font not installed on the crashing host. Then I re-ran the Windows Terminal and a default profiles.json was generated with which Windows Teminal worked fine.

Hey All ran into the exact same issue and realized that I didn’t even have a profiles.json. I ended up going into “Add or Remove Programs” and repairing Windows Terminal, fixed the problem for me.

I’m having a similar issue albeit with a slightly different Windows version.

I’ve tried removing the application using Add/Remove Programs, it has never successfully run on this host.

@uberubert The “Repair” option is under “Advanced options”

Worked for me.

For WT 0.3.2171.0, it seems that for a profiles.json with invalid font Windows Terminal will now fallback to a default font (seems like consolas to me) instead of crashing. For now I don’t see any necessary to keep this issue open and I’m closing it.

But still, no warnings are raised to remind users to fix their profiles.json.

I am experiencing the same issue and WT stills always crashing even after restart, reinstall, and a new Windows update.
