My usual boilerplate - hit it with a hammer - suggestions:
Notice the BraveSoftware folder in the following path:
%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default
Exit / Quit everything.
Move that folder to the Desktop.
Restart the Windows OS machine.
Change the path within the Brave Browser shortcut on your computer’s Desktop, to include switches that are intended to:
- Start up Brave Browser, showing a New Private Window
- Disable all experiments at
brave://flags - Disable extensions
- Disable GPU ie disable Hardware Acceleration
- 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 Windows OS Desktop
The Brave Browser executable, brave.exe, is located in one of:
64 architecture
"C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe"
x86 architecture
"C:\Program Files(x86)\BraveSoftware\Brave-Browser\Application\brave.exe""
Changed Paths:
64 architecture (change the path to):
"C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe" --incognito --no-experiments --disable-extensions --disable-gpu --enable-leak-detection --crash-on-failure 2> %USERPROFILE%\Desktop\brave_console_out.txt
x86 architecture (note the switches to add):
"C:\Program Files(x86)\BraveSoftware\Brave-Browser\Application\brave.exe" --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.
Here, hoping that Brave Browser runs. It will create a new “BraveSoftware” folder in the aforementioned path.
When you think appropriate, restore the Brave Browser shortcut . . .
64 architecture
"C:\Program Files\BraveSoftware\Brave-Browser\Application\brave.exe"
x86 architecture
"C:\Program Files(x86)\BraveSoftware\Brave-Browser\Application\brave.exe"
