**Description of the issue: Brave Browser will not launch on Windows 11. **
How can this issue be reproduced?

  1. I try to launch the browser, and it will not launch.

*Expected result:Browser launches.

Brave Version( check About Brave):134.1.76.74 presumably

**Additional Information: I have completely uninstalled Brave, including with Revo Uninstaller, deleting all folders and registry keys. I backed up user_Data to my desktop, hopefully I can recover my bookmarks.

I have rebooted several times, including after reinstalling and after install of the latest version from https://brave.com/download/

I click the desktop shortcut, the executable directly from the folder, everything, but it will not launch.

I am running W11 23H2, 22635.4440 , Windows Feature Experience Pack 1000.22700.1055.0

i7-12700k, 32 GB RAM, 64-bit operating system, x64-based processor

Brave is installed on C: drive

Nothing has changed in my environment that I can think of, before this started occuring. **

You might verify the installation

Brave Browser installation location on Windows OS

Application “brave.exe”

64 architecture

C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe

The initial Brave Browser Profile is, by default, named “Profile 1” (unless you change that name → brave://settings/getStarted).

The folder that contains the initial Brave Browser Profile, is the Default folder (a name that you must not change):

C:\Users[UserName]\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default\

That path may also be written:

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\

%USERPROFILE%\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default\

If you create 1 additional Profile (aka “Profile 2”), it will be stored in folder Profile 1:

C:\Users[UserName]\AppData\Local\BraveSoftware\Brave-Browser\User Data\Profile 1\

If you create a 2nd additional Profile (aka “Profile 3”), it will be stored in folder Profile 2:

C:\Users[UserName]\AppData\Local\BraveSoftware\Brave-Browser\User Data\Profile 2\

IMPORTANT - Replacing Profile folders

When replacing Brave Browser Profile folders:

Folder named Default (including its contents) can only replace its likeness: the folder named Default.

Folder named Profile 1 (including its contents) can only replace its likeness: the folder named Profile 1.

Folder named Profile 2 (including its contents) can only replace its likeness: the folder named Profile 2.

IMPORTANT - Brave Browser Preferences

Some Brave Browser Preferences are stored in the Preferences file:

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\Preferences

The contents of that Preferences file, are not exactly the contents of, brave://prefs-internals/.

Some Brave Browser Preferences are stored in the Local State file:

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\Local State

Bookmarks and Bookmarks.bak files:

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\Bookmarks
%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\Bookmarks.bak

Cache (folder):

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\Cache\
