IFR in flight map FREEZE

has anyone else out there encountered a complete freeze when clicking IFR map mid flight ? i know it was an issue months ago but it happened to me this morning, got up nice and early to do a 5 hour flight,
i was using the DREAMLINER and straight away FPS seemed shocking at the airport gate, but once took off everything was fine fps were great ( locked them to 30fps yest ) then 45 mins into flight clicked the in flight IFR map and it comletley froze ?

im using a gaming laptop

i7 10750H
16gb ram

using 5 fan cool pad
fans on max
average temps mid 70s so cant see it been temp problem ?

any help would be great.
