Two CTDs in two flights back to back

ISSUE DESCRIPTION

Description of the issue:
On Sunday night I attempted KLAS to EGLL in the PMDG 777W in 2020. About six hours into the flight, a total crash to desktop with no warning messages.
Tried the same flight last night and again about five to six hours into the flight a CTD.
I’ve done hundreds of flights across the atlantic in the PMDG 777 without problems and haven’t changed any settings or add ons.
