I have the same problem. The only solution I found to workaround this problem is by running:
brave-browser --ppapi-flash-path=/usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so --ppapi-flash-version=32.0.0.114

@ikus060, this solution doesn't work for me on Linux Mint 18.3 Sylvia and Brave 0.68.132 Chromium: 76.0.3809.132. I have the standard adobe-flashplugin package installed, it provides flash player version 32.0.0.238, but changing 114 to 238 in your solution doesn't help, flash plugin is not listed among chrome://components and doesn't start on flash sites, even though enabled in per-site settings.

Oh, and of course I symlinked /usr/lib/adobe-flashplugin to /usr/lib/pepperflashplugin-nonfree
That didn't help either.

This worked perfectly for me on Mint 20.

sudo apt-get install pepperflashplugin-nonfree
sudo update-pepperflashplugin-nonfree --install
sudo sed -i -e '/Exec=/usr/bin/brave-browser/s/$/ --ppapi-flash-path=/usr/lib/pepperflashplugin-nonfree/libpepflashplayer.so --ppapi-flash-version=32.0.0.344 /' /usr/share/applications/brave-browser.desktop
