FS fails to update - looping

My problem is that when decompressing a large file, frequently it will stick. Last night is was decompressing and 8 hours later it was still doing so. I’ve been using Task Manager and when disk activity stops for awhile (5 minutes or so) , I stop the update, close MSFS, and erase the file it was stuck on. This works a lot of times, but some times the program will start load all files all over again. I have been trying the update to 1.12.13.0 for over 36 hours and it is starting to load the files AGAIN!. On the last update, it took over a week to complete the update.

Why can Microsoft not fix this problem?
