I had the exactly same problem you've posted.
I solved it partly by going to Task Manager and, under Service option, restart the HIDSERV service.
And that's it. All that same keyboard with issues started working fine.
Here's the site from were I got that idea:
Some keys are not working after windows 11 update - Microsoft Q&A
I was writting this solving post when the "1" keyboard started to non-function again. What a pitty.
But, nevertheless, this improve is better than nothing.
