Game takes 5-10 minutes to load to main menu on first load of each day

Steps to reproduce

1. Boot up your computer.
2. Double-click Minecraft.

Expected result

Minecraft loads to the main menu within a minute. It may use some time and system resources to authenticate my device and login credentials, check for updates, and download and install UI updates, but it should not appear to be stuck on unchanging screens for minutes at a time, nor should it be keeping the hard disk near 100% busy for 10 minutes straight.

Observed result

The first time Minecraft is loaded under each account on my PC each day, it takes 5-10 minutes to get to the main menu while accessing the hard drive to 100% capacity the whole time. It appears to hang for several minutes on the blank red screen and then for several minutes again at 41% on the loading screen. When it finally gets to the main menu it often shows the vanilla resource errors described at MCPE-145110.
