Certain keys randomly stop working on my MacBook Air often.

Can't type certain letters on my keyboard at random intervals

For the record, I'm typing this on my phone because it came out like complete nonsense on my mac. I've had my mac for about 2 years now with no similar issues, and lately I've been getting this problem where I can't type certain letters/keys on my keyboard. Specifically e, d, 3, F3, F11(The VOLUME DOWN BUTTON), & the escape key. At first it was happening at random short intervals for random durations but now it seems to be getting longer and longer each time. It is most likely not a physical problem with the keys because this always happens, and started happening, at the same time for all four keys. This is extremely irritating and I have no idea the source of the problem. The only thread I could find talking about the same issue is [this one](https://discussions.apple.com/thread/5982152?sortBy=best). Problem is none of those solutions have worked for me. If anyone else is having the same issue or better yet has a solution, please help. 🙏
