Kind of a vague question, if your keyboard doesn't have n-key rollover, you can see the issue crop up. If you have malware on your platform, that can also lead to the issue mentioned above, if you have a game with stowaways then that's also another possibility.
How about you mention what the make and model of your keyboard is and what titles are affected with the issue you speak of...? A regular laptop might not be built for gaming, just my 2 cents on the matter.
I really didn't know how to ask it honestly, probably why I could only find a few topics online.
Here recently if I'm playing cod with a browser open ( usually listening to music on opera browser, tested other browsers as well the issue still happens) a select few keys will stop typing like H,V,T and backspace sometimes in the browser search window and in game chat, it will auto sometimes delete typing in the search bar only after 2 letters) if I hit shift that key will type a Capitol, like lower case h will not work but capital H will, just not a lowercase in the browser or in game chat.
If i minimize the browser everything's fixed until it starts again and I have to minimize again.
I can type in the browser, in notepad , in programs all day long if Cod isn't running keyboard works flawlessly.

Just giving you all my specs just in case you need them
Now that i think about it, this really started after i upgrades to windows 11 pro, and had to reset windows because of a lockscreen issue , which deleted the link between c drive and games drive (had to tell battlenet to relocate the games) could this be the issue and how would I fix it.
