Failed to install UEFI + wrong version

[MaxLysazwek]

Hi, I'm trying to install patch and I've got a few problems. First of all, I'm new to Linux and only understand the general idea of ​​what the commands do, but have no knowledge to fix errors below
So, I'm trying to install qemu and patch on (almost) clean debian-12.7.0 (with some rdp apps to copy-paste commands). Its installing with no errors, then i reboot pc to make sure all works after reboot, and then im trying to allow config from qemu-anti-detection (of course not a fully copypaste, just trying to undestand whats gui buttons sticked to xml-lines). First problem: cant setup UEFI (edit - preferences - new VM), error screenshot:

Second problem is: i don't quite understand how to make sure patch has been applied, so I expectedly just looked on the Internet how to find out the current installed version, and kvm --version or /usr/bin/qemu-system-x86_64 --version shown 7.2.13
I also tried clear install on Archlinux, and here i can setup UEFI config but as well, it shown wrong qemu version (9.1.0).
If this were Windows, i'd assume that qemu is sticked to Windows version and compilation is not working, or virt-manager can't hook correct qemu version, but we're on Linux and have no idea what's going on here, looking for help here
