ProbleMs with Macbook keyboard and brave

Spacebar, lower case U and M and now capital b don’t always work or work the way they shoUld, all of a sUdden. All at different tiMes, too. First it was jUst “U”, then the spacebar, “M” for started Messing Up today, along with “b”. The spacebar works intermittently only when I’M searching for soMething. When it doesn’t work, an eMpty blUe box appears on the screen. The box has no fUnction. Right now, I can Use the spacebar and lowercase M and U on the search field bUt not capital b. That jUst opens and new search window! This all happened after the last Update. I don’t have any of these probleMs with brave on My iPhone. I know it’s not My keyboard, I don’t have any of these probleMs in any other app.

I forgot to add that I had to change My password to log onto My coMpUter today. It woUldn’t recognise My password. Now I lost all y passwords on brave. Up til this week, I’ve loved Using this browser. I hope there’s a fix for this probleM that doesn’t involve redoing all My passwords ManUally.
