Same issue here in esxi 6.7 as shown in the first screenshot in this thread. I'm stuck on the copyright screen after pressing Alt + F1 and can't get out of it. It's been on that screen for over 24 hours now.
I set both of these to 10 seconds but it's not helping even after running this command to restart services /sbin/services.sh restart
Change UserVars.ESXiShellInteractiveTimeOut
Change UserVars.ESXiShellTimeOut
Is there anything else I can try besides restarting the host?
