I further suspect this is a bitwardon issue, others have the same issue.

This browser is no longer supported.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
Occasionally, the keyboard on my laptop seems to stop responding. However, it only seems to be alpha numeric keys, so I can't type the "L" key, but windows L works. The problem seems to be across all apps. Restarting resolves the issue, and it can be ok for a few hours or a few days.
I also had an issue once writing an amazon review. I could type into the title box, but not the description. Restarting the browser (edge) didnt work, but a reboot did. It seems similar to the main keyboard problem.
I've connected a usb keyboard and this has exactly the same problem at the same time.
Does anyone have any thoughts?

Try perform Clean Boot and see if the problem persist?

If problem have been solved, enable services one by one.
Try run Windows Update and install all updates.
