It looks like the command didn’t execute as expected because of a typo. The correct command should be:
ampinstmgr -a
Or, if you want to restart all instances with a delay between each restart:
ampinstmgr --restartallinstances
Give that a shot. You can also start individual instances using:
ampinstmgr -s [InstanceName]
So, for example, to start Satisfactory101
:
ampinstmgr -s Satisfactory101
Try running these commands and let’s get those instances up and running!
