Can't finish update because CTD in the middle of update process

I am in middle downloading package to 1.13.16.0 (London update). Two big packages remaining to download.

But, I can’t finish downloading because CTD occurs.
After I restart the game, it will redownload again fs-base-cgl-0.1.47.fspatch.00x and CTD again and so on, stuck in .005.

I have tried deleting all fs-base-cgl-0.1.47.fspatch.00x files and restart the game and it download from .001 again, but it worse! CTD happens and now it can’t download even first part.

I have severe CTD issues since Dec 2020, but this happens in middle of flight or loading menu, not on welcome/on boarding screen.

I’m thinking of giving up solution: complete update by copying someone’s MFS official folder packages to mine.

I don’t know if some people have this issue too.

Update:
I found some suspicous (or this is normal?) in Task Manager
MFS memory usage is increasing during download and I see it never decrease (from 2500MB till 3600MB now), at this rate I think this is possible my 16GB RAM run out.

Symptoms look pretty similar for me.

I still work on the initial activation of MSFS on my probably slightly aged i7 with 8GB and a graphic processor that seems to be a bit weak. Hence, I am not sure, where else I may have problems.

But after the initial 150GB download, I manged to enter the MSFS “hangar” only once and now the 1.13.16.0 package tries to load once more.

The progress bar indicates approx. 60% when the RAM load increases up to 4GB and the update finally crashes. No chance to enter the “hangar” - initiating the restart as abmin or normal user.

Did you get any valuable hints by now?
