Virtualbox: Machine UUID doesn't match its UUID

I'm trying to start my virtual machine, but it says Inaccessible. This is the error:

Machine UUID {66c1a081-b387-4a55-669a-0828d5d232ca} in 'C:\Users\{username}\VirtualBox VMs\Kali-Linux-2021.2-virtualbox-amd64\Kali-Linux-2021.2-virtualbox-amd64.vbox' doesn't match its UUID {001c9f74-feca-926c-23c2-0f5d47884876} in the registry file 'C:\Users\{username}\.VirtualBox\VirtualBox.xml'.

Result Code: E_FAIL (0x80004005)

Component: MachineWrap

Interface: IMachine {88562c68-b5bb-4426-a900-5eb28d3946df}

Why am I getting this error and how can I fix it?
