Windows 10: Why is my backspace, back slash, and enter key not working?

This just started today and I didn't change anything about my laptop. Yesterday, it happened for a few minutes, but then went back to normal so i just ignored it. I've tried resetting my computer, checking for updates, and cleaning under the keys. I've had this laptop for about 3-4 years; it's a Windows 11 made by Dell. I don't know what other information to add but if you need any more info just ask for it or something. please help i literally cant even type properly D:

:)

 

My enter, backspace, backward slash, and f5 key are not working. It has been happening for months recurringly.

I have a Windows 10 Pro, T14s computer. I have not been able to use the enter, f5 key, backward slash, and backspace key for times for months. The weird thing is if I spam the backspace key, it works for a while, but then starts not working. I have repeatedly tried checking the drivers, doing malware checks, and even uninstalling some apps. However, the issue keeps coming back, and even now I am unable to use the backspace key and am using the delete key instead. This is very inconvenient, and I want to know if there is any fix.
