Can you check if there are multiple instances of Quartus running in the background. Close all instances of Quartus, kill any unwanted programs running via Task Manager and then try launching Quartus again. I've only encountered this out of memory issue when targeting Stratix 10 devices which require a lot of RAM. You could also restart the system and then try again. If the system is a Server that caters to multiple clients, have the other users close the VNC sessions, Quartus tools and then try.
This issue should not occur with Max/Cyclone/Arria devices.
Open Task manager before invoking Quartus and note down the memory utilization. Then invoke Quartus and start the flow and note down the memory utilization.
I checked with my task manager, there are no multiple instances running in the background. Also, all unwanted programs has been killed. There is no way the design requires up to 162GB memory.
