[1.18.1] Why is gradle taking an eternity to set up a new mod??

[SapphireSky]

I've done this many dozens of times between 1.7 to 1.16 and every step of any commands needed to be run in gradle, either to initially set up the project or build it, has never taken more than 8 to 40 seconds to complete. My most recent gradle runs in 1.16 had finished all parts of the initial setup in just 24 seconds.

Now I'm trying to set up a new mod in 1.18.1 and I've never had something move so slowly in my life.

It takes about 30 seconds for this to show up: 

To honour the JVM settings for this build a single-use Daemon process will be forked. See https://docs.gradle.org/7.3/userguide/gradle_daemon.html#sec:disabling_the_daemon.
Daemon will be stopped at the end of the build

Then about 5 minutes later I get this:

> Configure project :

And after 26 minutes it finally starts doing something:

But when it moves to 'merge' it hangs yet again:

And at the very end, after typing all this and before I hit submit, it's only gotten this far with a weird requested stop message?:

 > Running 'merge'
 > Running 'listLibraries'
 > Running 'rename'

I'm on Windows 11. Java, the JDK, my system and all drivers are fully up to date, I have 16GB of RAM and a Ryzen 5 3600 in case that's even somehow relevant, and I have a fully functioning 900Mb/s wired connection.

I've tried on both my OS' internal SSD, my external SSD, and an external HDD, all with about the same results. If anything, the SSDs somehow take even longer for it to start doing anything.

All other programs and Windows Explorer are blazingly fast at moving, reading and writing files as normal. It's JUST gradle.

What's going on here?
