Your: ‘opened the browser via command line, with all extensions disabled, as described, but with no result’
I am uncertain about the trailing part: ‘but with no result’ . . . means?

For the following, add the switches to the Brave Browser shortcut.
The switches (that will follow) 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
64 architecture (note the switches to add):
"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
You would add the following, in the Brave Browser shortcut:
--incognito --no-experiments --disable-extensions --disable-gpu --enable-leak-detection --crash-on-failure 2> %USERPROFILE%\Desktop\brave_console_out.txt
Add those to the end of the Target field’s existing string.
