When going into F-PLN page on MCDU to alter STAR and transition into LAX all systems freeze. the buttons and knobs still show animations but the numbers and pages do not change. The sim continues to respond and work although the aircraft is just flying in a circle at FL380. Just the displays are frozen up totally. The efb still works and is clickable through various pages. Everything latest versions RE aircraft package, enhancement package and MSFS, Graphics drivers etc..
