Brave Browser doesn't open - attempted to delete Sync account

I was deleting my Sync account in BraveBrowser when the app suddenly closed. When I try to log in again, it closes instantly. My data is in it; how can I recover it before it’s deleted?

In order to see if you can “just get it running” - using the command line:

"C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe" --incognito --disable-extensions --user-data-dir="%TEMP%\BraveNewProfile01"

Notes:

  1. --incognito → Opens the browser in private mode.
  2. --disable-extensions → Prevents all extensions from loading.
  3. --user-data-dir="%TEMP%\BraveNewProfile01" → Initializes a fresh Brave Browser User Data structure in that temporary folder named “BraveNewProfile01”.

More Notes:

  • %TEMP% is a Windows OS environment variable pointing to your Windows OS user account’s temp folder. Using it ensures a new clean profile every time. Location: C:\Users\[UserName]\AppData\Local\Temp
  • Make sure the path to brave.exe matches where Brave is installed. In a Brave Browser New Window, go to: ‘brave://version’ and scroll down to Executable Path:

A batch file (the script) to clear the user’s Temp folder, when you wish:

@echo off
REM Run as administrator for best results
REM Clear current user temp folder
:: Location --> "C:\Users\[UserName]\AppData\Local\Temp"
del /f /s /q "%TEMP%\*.*"
for /d %%D in ("%TEMP%\*") do rd /s /q "%%D"
echo.
echo TEMP cleared.
pause


Paths to the brave.exe executable:

64 architecture, system level installation:
C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe

x86 architecture, system level installation:
C:\Program Files(x86)\BraveSoftware\Brave-Browser\Application\brave.exe

64 / x86 architecture, user level installation (NOTE: you must substitute your Windows OS user account name for [UserName]):
C:\Users\[UserName]\AppData\Local\BraveSoftware\Brave-Browser\Application\brave.exe


Be prepared by backing up your data.

How to back up Passwords that are stored by Brave Browser

Scrolling down the webpage at:

https://support.brave.com/hc/en-us/articles/360018185951-How-do-I-use-the-built-in-password-manager

A note states:

Export Passwords - Selecting Download file will export all credentials you’ve saved in your browser as a .CSV file onto your system. Note that anyone who has access to your system will be able to open and view this file, so it is recommended that you delete this file once you’ve used the file for its intended purpose.”

Tips on how to encrypt that .CSV file:

Be sure to safely store a copy of that CSV file on an external drive.

How to back up your Bookmarks as an HTML file

Two ways to get to the Bookmarks Manager.

One way:

  1. Launch Brave and open the Main menu: newmenuicon.png
  2. Select Bookmarks --> Bookmarks Manager
  3. Open the More options menu at the top right
  4. Select Export and choose where you want to store the exported file.

Another way:

  1. In a new Brave Browser window, go to: brave://bookmarks
  2. Locate the “Organize” (vertically-arrayed 3-dot) menu button in the upper-right area of the window; click on that
  3. You should get a pop-up menu, in which you click on the “Export bookmarks” selection and choose where you want to store the exported file.

The exported file name: “bookmarks.html”

Be sure to safely store a copy of that HTML file on an external drive.

Hey! I just had the same issue as you.
To fix it, you need to go to the Brave UserData folder. On Windows, it’s located at “C:\Users\USERNAME\AppData\Local\BraveSoftware\Brave-Browser\User Data”. Look for the Profile folder where you deleted the Sync Account (in my case, it’s the “Default” folder), and inside that folder, delete a file called “Web Data”.

To recap: I managed to solve this problem by deleting the “Web Data” file at this path: “C:\Users\USERNAME\AppData\Local\BraveSoftware\Brave-Browser\User Data\Default”.

thanks I solved it the same way
