enter key suddenly not working on NLS Ereader display.

Good afternoon to all, Hope everyone is well. I notice that as of earlier today, my enter key is not sending messages or say pressing enter on a search box like it should. I am running IOS 26.2.1 and using an nls EReader 20 cell display. I have unpaired and repaired the display, and did a soft reset of the iphone to no avail. Another interesting thing is, when typing in my passcode to unlock the phone it now says no item found. To my knowledge nothing about the phone or commands have changed on my end. Anyone have any thoughts on this? Thanks in advance.
