Something for you guys to try as a workaround provided by Microsoft themself 
It could be that you run into the page file issue described above in which files are requested by a program (MSFS) which are not yet available as the dynamic page file size was not yet properly reserved by the OS (aka Windows) so this/these files cannot be read (as they are not there).
The solution is to manually set the page files size according to the article linked:
Workaround
To work around this issue, manually configure the size of the page file. To do this, follow these steps:
- Press the Windows logo key + the Pause/Break key to open System Properties.
- Select Advanced system settings and then select Settings in the Performance section on the Advanced tab.
- Select the Advanced tab, and then select Change in the Virtual memory section.
- Clear the Automatically manage paging file size for all drives check box.
- Select Custom size, and then set the “Initial size” and “Maximum size” values for the paging file. We recommend that you set the initial size to 1.5 times the amount of RAM in the system.
- Select OK to apply the settings, and then restart the system. If you continue to receive “out-of-memory” error messages, increase the “initial size” of the page file.
This will basically reserve a portion of your (fastest!) drive to act like RAM (nuff said) of a fixed size - the OS does not have to predict the size needed so files can just move in and stay there, ready to be collected by your CPU/GPU 
PS: set both (initial and maximum size) to the same value! If you got 8GB of RAM set both to 12288 MB, if you got 16GB of RAM try 24576 MB and so on (GB of RAM x 1024 x 1.5)
