Can't change Default system UI language in Windows 10

Question

I'm trying to install Windows 11 with an ISO File, but I can't use the option to keep my files and apps because the setup and my PC are in different languages.(My PC was imported from Netherlands, and I change all language settings to English (en-US)) When I try to change the language with DISM /image:C: /set-uilang:en-US, I get an error "Error 2. Unable to access the image."

Here's some screenshots:

DISM /online /get-intl (To get installed languages)

DISM /image:C: /set-uilang:en-US (Changing UI language, getting the error)

Tried to remove Dutch from lpksetup, but can't because Dutch is the system language

What I have tried so far:

• Changing permission of the whole C:/Windows folder to full control
• Tried to run the commands using that startup Command Prompt (I don't remember how to call it lol), getting the same error
• Deleted the Dutch language packs from Settings app
• Tried re-installing Windows 10 (using another ISO file), getting the same error as installing Windows 11
• Change system locale to English (United States)
• Tried installing by booting USB with setup, doesn't work

Here's my Computer info (in case it helps(??)):

(Edit) And Language List from command Get-WinUserLanguageList: (nl-NL isn't appearing in this list)

Hi, Igor_Roggy. I'm Robinson, and I’m happy to help you today.

You can try this procedure to set the en-us as the default system language.

1-Click on Start then click on Settings

2-Click on Time & Language, then click on Language

3-Click on "Administrative language options" (on the right side of your screen)

4-In the new window, click on the Copy Settings button.

5-There are 2 checkboxes there you need to click("Welcome screen and system accounts" and "New user accounts") and after this click on Ok to save the settings and reboot your computer.
