MalfunCtioning of a letter on web pages

SinCe 2 days, I Can’t write the C in text boxes in Brave browser. It works in the address bar but not on aCtual pages. It only reads the Capitalized letter, that’s why I write like that.
I don’t know why it happened and how to resolve this issue. I’ve already tried to restart the browser, Change some settings, but nothing has Changed. It works on other browsers or apps.
Please help me solve this.
