Sorry for delay. I took a break.
I found a topic that had a similar error issue. Posting at the end below. It has links to two external articles and I am also posting two more. And guess what, renaming .exe is a workaround in the articles! I definitely wouldn’t have thought that.
I did a search on other topics in the Community and the most common fix in those topics appears to be right clicking the Brave icon, opening Properties, and inserting
–disable-features=RendererCodeIntegrity at the end of the string in the Target field. This is a post with a screenshot: Aw, Snap! Something went wrong - #37 by pradhyu89
If you can get to brave://crashes, can you check to see if there are any crash reports there? If inserting the flag at the end of the .exe target doesn’t work, it is probably way past time to call in the big guns, aka Brave support staff, to help. Just tag them in your next update if you are still having problems.
