Help needed Qubes 4.2.4 installer freezes on Lenovo X Carbon 7

[Newbie0625]

So I tried several Times over the last weeks to install Qubes 4.2.4 on my Lenovo X Carbon Gen 7 which has 16 GO Ram.
Basically I tried to do so on an external SSD drive. It failed despite trying different USB key and tweak that I found working for some people ( adding some lines in Grub). Did not work. I finally bought 2 new USB key and it worked to some extent. Problem is Qubes does not have access to internet ( WiFi). When I plug an ethernet cable it freezes. Since this should be related to the sys USB or something like that I decided to partition my computer hard drive. Now it again freezes at any moment after the installer appears. I m starting to drive crazy. I tried to add the cpufreq=xen:hwp=off command on Grub does not do anything. I tried chatGPT . Its advices did not work.
Could anyone help ? Because I really want to use Qubes but now I m on the verge of quitting.

Without applying the 3. Because it was causing a crash as well

« When booting the system from USB, press the “e” key to edit the selected boot entry (usually “Install Qubes OS R4.2.x”).

1. Add the nomodeset parameter at the end of the line starting with module2 /images/pxeboot/unlinuz. This tells the kernel not to load graphic drivers until the boot process is complete, which may resolve issues with incompatible drivers.
2. Replace quiet with plymouth.enable=0to disable the graphical Plymouth boot screen and display text-based messages during boot, which may help identify errors.
3. Add the efi=attr=uc parameter at the end of the line starting with multiboot2 /images/pxeboot/xen-gz to help with potential UEFI-related issues.
4. Add the parameters modprobe.blacklist=xen_acpi_processor rd.driver.blacklist=xen_acpi_processor to the line starting with module2 /images/pxeboot/unlinuz to block the xen_acpi_processor module, which in some cases has caused installation hangs on ThinkPad laptops.
5. Press F10 or Ctrl+X to boot with the modified parameters. »
