Exceptionally long duration of "Downloading index: ..." process

Describe the problem

I know a number of people have reported this problem for months but still it isn't solved.

When starting Arduino IDE 2.2.1, notification area shows "Downloading index: library_index.tar.bz2"
Progress bar stays at 50% for a really long time, like 1/2 hour.

I know it isn't an issue of accessing the Internet, as I am writing this connected to the Internet with Arduino stuck at that stage.
Even if I didn't have an Internet connection at the time, IDE should time out after maybe a minute and move on with its life.

While it is in this state, can't compile, as compile progress seems to wait for the index download to finish

Once I get past this, then successive launches of Arduino seems to be good either for the rest of the day or as long as I don't log out of Windows, haven't figured that part out yet.

To reproduce

Start Arduino IDE 2.2.1 for first time in a particular day

Expected behavior

Not get stuck for 10's of minutes with status "Downloading index: library_index.tar.bz2"

Arduino CLI version

0.34.0

Operating system

Windows

Operating system version

Windows 11

Additional context

It downloads instantly if I use my web browser to download the file:

https://downloads.arduino.cc/libraries/library_index.tar.bz2

The fault does not occur If I run Arduino CLI directly:

C:\Program Files\Arduino IDE\resources\app\lib\backend\resources\arduino-cli core update-index

It hesitated about 10 seconds, with seemingly successful results:

Downloading index: package_index.tar.bz2 downloaded

Looking at the terminal logs, the Downloading Index seems to take a long time doing these while the fault is occurring:
