Weird keyboard issue

[king1]

right click the start menu -> system

under windows specifications or similar , if it just says windows 10 without the PRO it is probably home

Windows 10 Pro

I also just had the issue crop up again in a word game. Transferred the URL over to Edge and problem wasn't present, and also had cured the problem when I went back to the page in Firefox. (Same result as inputting into Excel).

try Firefox in safe mode for awhile
settings -> help
troubleshooting mode

If its ok then it would suggest an extension causing the problem...
