Opening multitasking view after disconnecting external monitor crashes the secure session

What Happened?

If I start a secure session with an external monitor connected to my laptop and eventually disconnect that monitor, open windows are moved to the laptop screen, as expected. After that, however, if I enter multitasking view (either by clicking the shortcut in the dock or by using a keyboard shortcut), the entire session crashes and I get sent back to the login screen. This is consistent in my setup and I am able to reproduce the issue through the steps described below.

In my setup, the external monitor is configured as the primary display (i.e., where the dock and the panel show).

I am using the RC for OS8 and I have run all updates.

Steps to Reproduce

Have a second monitor connected to laptop before logging in.
Log in to the secure session.
Open any app on either monitor.
Disconnect second monitor.
Enter multitasking view.

Expected Behavior

I would expect to enter multitasking view with no issues to be able to quickly reorganize my windows.

OS Version

8.x (Early Access)

Session Type

Secure Session (Wayland)

Software Version

Latest release (I have run all updates)

Log Output

No response

Hardware Info

Processor: Intel Core i5 8250U @1.6GHz Graphics: Intel UHD Graphics 620 Dedicated graphics card: AMD Radeon 535 RAM: 8GB

Laptop screen resolution: 1920x1080 External screen resolution: 2560x1440

I can reproduce the issue somewhat 1/ disconnecting the main/only monitor 2/ opening multitasking 3/ connecting the main monitor

on reconnecting the monitor i hear my BT speaker do the disconnect / reconnect sound, and my monitor wake up to lightdm. i cannot determine looking at dmesg, but there is this line
