So, after many tries, make my drive with all zero and try to format with btrfs, xfs and it always failed at some point of the install i found a solution here : https://superuser.com/questions/1688659/128gb-emmc-drive-on-asus-laptop-unable-to-format-to-ext4
On this page it says " It seems the laptop has eMMC controller with buggy CQE implementation.
Since linux kernel version 5.5 it is possible to make system avoid using CQE by specifying debug_quirks=0x20000 option to sdhci module. (0x20000 is the value for SDHCI_QUIRK_BROKEN_CQE flag in sdhci.h). After properly propagating the option I was able to install and use Ubuntu 20.04 with ext4 rootfs on the eMMC drive of this laptop."
So basically when i was in live cd mode i did this :
sudo modprobe -r sdhci_pci
sudo modprobe -r sdhci
sudo modprobe sdhci debug_quirks=0x20000
sudo modprobe sdhci_pci
After that i try to launch the calamares installer and i left all the default parameter, erase all the disk, make ext4 partition and i just check the swapfile option and everything went right !
The only thing now i’m not sure how to do it is to make a conf file for modprobe, i did try to make a file in /etc/modprobe.d with “options sdhci debug_quirks=0x20000” in it but i don’t know how to make manjaro use it at boot. For now i have succed using my manjaro with adding " sdhci.debug_quirks=0x20000" on grub when i boot and everything work, i just have to increase my swapfile file (why only 512M ? why can’t we choose at the install ?).
If someone can just tell me how to boot with sdhci option so i don’t have to go into the grub menu, and when it’s done i can mark this as solved !
