Used Find Any File to search for all Brave files. Moved to trash. Emptied trash. Redownloaded Brave and installed. Modified System Security to allow Brave to launch. Brave starts to open, then closes.
Opened Brave package contents, went to Brave Mac Os folder and launched the terminal command there, and got the same results, along with this error message on the terminal:
