Unable to type b capital (shift+b)

How can this issue be reproduced?
Open any web mail client in brave browser. In my case: protonmail
Try to type capital b (shift +b). Nothing happens. In the address bar of brave browser it works Ok.
In Firefox browser, it works Ok. In Libre Office, it works Ok.
I turned off all the extensions: did not work.
Typing b letter (no shift+b) works Ok.
This happens since a few weeks ago.
Expected result:
b letter appears in capital.
