Crash when attaching to browser and same chat is not in main window

[c0ldplasma]

Describe the bug When trying to attach a chat to browser which is not open in the main window chatterino crashes. When opening it first in the main window it works.

To reproduce Try attaching to browser on a channel which is not open in the main chatterino window.

Chatterino version Chatterino Nightly 2.2.3-beta2 (commit cfa9e59, )

Operating system Windows 10 20H2

I tried to debug the issue but it seems when building and running chatterino in Qt Creator it does not attach to the browser, only standalone builds do.

Any idea how to debug this?

If I understand this issue correctly, it only occurs when there's no channels open?

It occurs when the exact channel I try to open in browser is not already open in the main chatterino window. Regardless of whether there are other channels open or not.
