Windows 11 24H2 installer crashing from a ventoy USB

[Eliott]

For a friend, I install (from scratch) with my ventoy stick a French W11 24h2 without problem 2 days ago.

What's your config ?
If this helps you solve your problem.

My Ventoy flash drive (Sandisk Ultra 128Go):
Secureboot Off
MBR partition
Formatted in NTFS.

The (7 years old) Laptop :
Bios config:
“Legacy” mode
Secureboot off
Sata SSD:
NTFS format on MBR partition.
