When I start Virtualbox 6.1.8 a different vm is selected, but as soon as I choose ""manjaro-kde"", Virtualbox just freezes and can't be closed. The GUI X button is greyed out. I have to use Process Explorer to kill it, and after that can't be relaunched until I reboot. At least UI should provide several ways to fix it, not freeze and forcing a reboot. {{{ Oracle VM Virtualbox Manager manjaro-kde: Inaccessible Could not find an open hard disk with UUID {68875579-5923-4090-b612-f672cb93c5ff} Result Code: VBOX_E_OBJECT_NOT_FOUND (0x80bb0001) Component: VirtualBoxWrap Interface: IVirtualBox {d0a0163f-e254-4e5b-a1f2-011cf991c38d} }}} Forum thread: https://forums.virtualbox.org/viewtopic.php?f=6&t=98232",enhancement,new,GUI,VirtualBox 6.1.8,,,,Linux,Windows
