I have installed brave on my desktop and laptop, both with Win 10 1903, x64.
Kaspersky Internet Security (latest version) added an addin in brave but only on the desktop.
In these 2 days brave chrashed several times on both systems. All brave windows suddenly are just gone. No crash message, nothing.
I enabled send crash report.
Hope you can fix thaT soon.
Never had these problems with firefox or chrome.
