Greetings and salutations.
That is, unfortunately. I help running a website for a cleaning company
https://prorengoring.dk/ where we had some issues with animals and electronics :)
But I don't think this is the problem here. I always had experiences with Lenovo and installing windows 10. I don't know if you had windows 10 before, but when I installed it, the problem was, that Lenovo had made so little space on the hard-drive, that there wasn't enough space for the upgrade. Otherwise, it can just be the virus that destroyed it :/ Don't blame the cat :)
