Comments/Problems:

Installing debian testing (Trixie) with the "graphical install" option is not possible, the process stops immediately after launch, with a black screen and a line at the bottom left with the following text: "E: unimplemented function".
At this point the PC is blocked and a hardware reset is required to restart.
ISO image verified with sha256.
I attach photos of the screen on which the block of system occurs immediately after launching the installation.
