Please disable all of your other (than Brave) Internet browser’s extensions that are anti-virus. Exit / Quit everything and Restart your computer.

For the following testing: You might disable any anti-virus software OTHER THAN Windows Defender.

Requires some study:

If Brave Browser starts AND continues to run, then be prepared for:

How do I manually submit crash reports?

https://support.brave.com/hc/en-us/articles/22281484910221-How-do-I-manually-submit-crash-reports

After you click the “Send Now” button, return to brave://crashes and gather up the Crash ID numbers. Post the numbers, here, in a new reply.

Without BB running, please delete the following items:

Caches (folder):

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

Cookies (file):

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

Sync Data (folder):

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

About that Sync Data folder, see:

Slow browser startup [Reason found, Potential Bug? Pls dev] - #11 by TheDuke203

Re deleting that folder, “fixes” a Brave Browser “Slow Startup” issue. So, maybe you will get lucky, here, too.

Alternative to using the Command Prompt window . . .

Change the path within the Brave Browser shortcut on your computer’s Desktop.

For the following Changed Path, the switches are intended to:

  • Start up Brave Browser, using the “Default” named user Profile folder [--profile-directory="Default"]
  • Showing a New Private Window [--incognito]
  • Disable all experiments at brave://flags [--no-experiments]
  • Disable extensions [--disable-extensions]
  • Disable hardware (GPU) ie Graphic Acceleration [--disable-gpu]
  • Enable leak detection and if that failure occurs, then crash the browser [--enable-leak-detection --crash-on-failure are a combo]
  • Produce error/log output to a file named ‘brave_console_out.txt’ on the Window OS Desktop

Changed Path:

64 architecture, system level installation:

"C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe" --profile-directory="Default" --incognito --no-experiments --disable-extensions --disable-gpu --enable-leak-detection --crash-on-failure 2> %USERPROFILE%\Desktop\brave_console_out.txt

x86 architecture, system level installation:

"C:\Program Files(x86)\BraveSoftware\Brave-Browser\Application\brave.exe" --profile-directory="Default" --incognito --no-experiments --disable-extensions --disable-gpu --enable-leak-detection --crash-on-failure 2> %USERPROFILE%\Desktop\brave_console_out.txt

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" --profile-directory="Default" --incognito --no-experiments --disable-extensions --disable-gpu --enable-leak-detection --crash-on-failure 2> %USERPROFILE%\Desktop\brave_console_out.txt

Notice that the existing path, BEFORE the additions, is enclosed by double-quote marks. And, everything added to the existing path, is located after the existing path.

BEFORE DOUBLE-CLICKING ON THE SHORTCUT locate the “Default” folder:

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

. . . and Open it. That may help, by bringing that specific folder, to the interested processes’ more-immediate attention. (And was a tip, that I found, re using --profile-directory="Default".)

Examine the error/log output file named ‘brave_console_out.txt’ on the Window OS Desktop. The file might contain information.
