question about jaws and Windows 11

at work, I use Windows 11 and Jaws, version 23, I think. I had a strange occurrence today. I locked my computer to go on break, and when I came back, Jaws kept saying not in table. When I tried to hit old F4 to get out of, whatever it thought it was in, it kept saying alt shift F4, which didn’t make any sense. I finally had to reboot the entire system to get it to speak properly. Does anyone know why Jaws might have done that?
