Xfce, Kernel 6.12.25-1.
All went almost fine, except for the fact that, during the process of upgrade, I received an error message about the fact that the file /usr/lib/firmware/rtw88/rtw8814a_fw.bin already exists on the file system.
This file is owned by the package rtw88-dkms-git, and is absolutely needed for my USB WI-Fi adapter: TP-Link Archer T9UH v1 [Realtek RTL8814AU]
How I solved: sudo pacman -R rtw88-dkms-git and as expected, after the reboot, I had no functional Wi-Fi adapter.
Luckily I used the USB Tethering of my smartphone, to reinstall the package rtw88-dkms-git to have again the Wi-Fi adapter functional/recognized by the system.
I use rtw88-dkms-git since months, and this conflict never occurred.
I’m going to make a dedicated post about this issue.

Done:
