@philm from Manjaro Team gave me the clue:
Reading Mesa’s forum there are more people with similar problems.
I’ve read somebody telling Mesa 24.0 solves the issue. Until then, I have this line in pacman.conf to avoid all the 23.3.3 packages:
IgnorePkg = lib32-libva-mesa-driver lib32-mesa lib32-mesa-vdpau lib32-vulkan-intel lib32-vulkan-radeon libva-mesa-driver mesa mesa-vdpau vulkan-intel vulkan-radeon
