“Page Fault In Nonpaged Area” usually results in a BSOD and can be quite frustrating to troubleshoot. The error is caused by Windows not finding a file within memory that it expects to find.
I would first check in your BIOS what speed your RAM is set at and what XMP profile is used.
MSFS does use the GPU first for installing. Another thing to check is the virtual paging (memory) file in Windows.
