I took it to our tech support, after spraying air and all the recommended steps they could not fix it. They took it and gave me a new one.
After a month, the 'B' key on that new laptop started to be flaky.
Unless Apple manages to fix this, my next computers at both work and home will not be Macintoshes. After over a decade of loving Mac laptops, I will either be switching over to Windows (WSL looks great) or Chromebooks.
