I had the same issue for 2 days. After uninstalling and reinstalling even an old version of Brave. And also Chrome and Adobe reader, it still gave the same “Aw, Snap!..” error. So I just uninstalled and assumed something on my computer was corrupted.
After checking here just in case and seeing that other people had the same exact problem, I reinstalled and figured I’d wait on Brave showing an update available.
But after downloading again and installing, it works just fine. Version 1.1.21 Chromium: 79.0.3945.79 (Official Build) (64-bit)]
So either there has been some update to either Brave or some other program that was messing things up, or whatever else I did, fixed the issue.
Edit: I spoke too soon. I had a weird issue which is it seemed to work normally, but then went back to giving the error for new tabs. However, for a while I had one tab that worked normally as I could click any link on the page an it opened that link just fine. But I could not type a different URL into the bar and have it go to that page. It blipped for a fraction of a second and the page didn’t change and the original url just came back in the bar. Right clicking and trying to open a link in another tab or new window gave the error in that new tab or window.
That one tab worked just fine as long as I had it open. So the browsing functionality seems to work just fine.
I closed the browser and opened it again and am back to the error.
