Oracle VBox inaccessible after change of name of user folder on Windows 10

Yesterday I changed name of my user file and name of account from "Król" to "Sotel" on Windows 10. Now my oracle vbox is inaccessible and shows error:

Runtime error opening 'C:\Users\Kr�l\VirtualBox VMs\SW\SW.vbox' for reading: -103 (Path not found.).

F:\tinderbox\win-6.1\src\VBox\Main\src-server\MachineImpl.cpp[754] (long __cdecl Machine::i_registeredInit(void)).

Score number (RC): E_FAIL (0x80004005)

Component: MachineWrap Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

I have already changed path to "C:\Users\Sotel\VirtualBox VMs" from "C:\Users\Król\VirtualBox VMs" in tab "general" in global settings of oracle virtual machine but it doesn't solve the issue. What should I do to make my vbox accessible again?

Solution was to remove the VM from the list of VMs (that reference the incorrect location) within VirtualBox and add the VM in it's new location.
