Expected Behavior

Rancher starts normally.

Additional Information

This bug is intermitent. It only happens every other Rancher start. Sometimes it starts fine, other it crashes Windows Terminal.

This is Windows 11, and Windows Terminal Preview is the default terminal:

What I believe is happening is that Rancher is running several scripts in a visible way, and they get to open on Windows Terminal. I notice that Windows Terminal gets focus several times during Rancher desktop launch, and a tab opens and disappears very fast.

For some reason this is making Windows Terminal crash.

Also, Rancher desktop does not finish starting when this happens.

I tried changing the default terminal to the Windows console host, and the error does not happen anymore. I started Rancher desktop several times and could not see it anymore.

Once I changed back, the behavior happened again. It is definitely the fact that Windows Terminal is the default terminal that is leading to this.

The problem does not happen with Windows Terminal, only with the preview, which is release a month sooner. I just updated mine today with a recent version, it is version 1.13.10336.0.

How exactly do you launch Rancher Desktop?

[stefanfritsch]

You can change the title back, this also happens to me on a release version of Windows Terminal (1.12.10334.0).

I've installed Rancher Desktop with winget, then I open it from the start menu. It tries to install kubernetes (dockerd, v1.22) but if the default console host is Terminal then it hangs indefinitely. Switching to the Console Host solves the problem.

I launch it from the Windows Start Screen or from Windows Power Toys Run.
