Suggest that you study:
Brave does not launches, even after deleting User Data - #39 by clifton
and from there, on down that page, for ideas on what to do.
In particular, the Brave team member who would be interested in your crash data and logs, seems to be @szilardszaloki - as you will see in your reading that page.
Also, the following might eventually work:
https://support.brave.com/hc/en-us/articles/22281484910221-How-do-I-manually-submit-crash-reports
And, you should have a file, now, on your Desktop:
“brave_console_out.txt”
