Virtualbox home assistant VM keeps crashing

For a few weeks now, I’ve been experiencing frequent crashes of my virtualbox VM running home assistant OS. VirtualBox is currently running on my main machine, planning to migrate it to an HTPC later. I have a 3 monitor setup (seems relevant given the error messages below) on Windows 11. The crashes always follow the exact same pattern, but sometimes it happens every half hour, sometimes its many hours in between. 5-10 minutes before the crash, I start getting log messages like this:

06:13:09.257952 GUI: UIDesktopWidgetWatchdog::sltHandleHostScreenResized: Screen 1 is formally resized to: 2560x-220 x 1080x1920
06:13:09.257972 GUI: UIMachineLogic: Host-screen geometry changed
06:13:09.258035 GUI: UIDesktopWidgetWatchdog::sltHandleHostScreenWorkAreaResized: Screen 1 work area is formally resized to: 2560x-220 x 1080x1920
06:13:09.258044 GUI: UIMachineLogic: Host-screen available-area changed
06:13:09.258075 GUI: UIDesktopWidgetWatchdog::sltHandleHostScreenResized: Screen 2 is formally resized to: -1080x-220 x 1080x1920
06:13:09.258100 GUI: UIMachineLogic: Host-screen geometry changed
06:13:09.258132 GUI: UIDesktopWidgetWatchdog::sltHandleHostScreenWorkAreaResized: Screen 2 work area is formally resized to: -1080x-220 x 1080x1920
06:13:09.258137 GUI: UIMachineLogic: Host-screen available-area changed

And I then get many hundreds of those over the next few minutes. This is then followed by a crash

06:17:21.224748 !!! rtR3WinUnhandledXcptFilter caught an exception on thread 0000000000008888 in 35108 !!!

I’ve tried changing the graphics controller for the VM and even turning it off completely, but I still get the exact same failure mode.

Has anyone ever experienced something similar? Any suggestions what I could try to fix this issue?
Thanks!

Try with ich9 board/chipset
