problem solved
I rebooted, selected the previous fc41 kernel
sudo dnf remove kernel*6.14.2*
sudo dnf upgrade --refresh
Though then I had to do a lot of manual work.
For example, restore virtualbox.
Actually, I’m still eliminating the consequences of the disaster.
I have 2 more laptops with LXQt and a desktop with Cinnamon
I’m even afraid to update them…
