I've seen this on 18.04, 20.04 and now 22.04 (maybe on 16.04 but not sure), I  
never chased it up, assumed it was hardware on that box, A Dell, it just sits 
on "F2 F12" window, so I tend to 

"shutdown now -P" 

then power on again, the box "should" boot from keyboard key but it has never 
worked that way, it's a Wireless USB KB so that may explain it
