Do it yourself! Its not too hard, ill explain it here. (altho some basic unity knowledge is required)
Note: This will give you a recovered project, not a unity package, extracting to unity packages breaks everything from my experience, and is not recommended. (you can still ctrl+x the folder to merge it with a different project)

1. Download SARS (ARC): https://github.com/Dean2k/SARS
   2.Clear your cache, then restart vrc, preferrably with you already being switched into the avatar, either via vrcx or the website.
2. Wait for it to download and for you to load into the avatar.
3. Go to C:\Users\yourusername\AppData\LocalLow\VRChat\VRChat\Cache-WindowsPlayer, if you cleared your cache, there should be one folder, and only one.
4. Rename the _data file to _data.vrca
5. Open SARS (ARC)
6. Open the VRCA Information tab.
7. Click on "Load VRCA/VRCW", then select the _data.vrca you renamed before.
8. Click on "Extract VRCA/VRCW"
9. Under the install folder of your SARS (ARC) installation, youll find a folder called "VRCA", the extracted project will be in there, either drag it into the assets folder of your main project, or import it into VCC by clicking on the arrow next to "Create New Project", then clicking on add existing project.

Seen that hair on a few rusks before.. I whould personally just rip it, delete everything else except the hair from that rusk, then merge the armatures with the rusk youre actually working on.

May not be the most optimized, doing this sorta stuff you can be very sure youll be on very poor, but it works.

I whould like to add something to this:
If you extract the VRCA with asset ripper, things are gonna be absolutely f*cked, lot of missing scripts that you will have to fix
There is a way around this!
The tool A.R.C. (previously S.A.R.S.) while it is primarily a avatar downloader it also has some very handy VRCA extraction tools that are really handy.
Almost all things youll use here will be under the VRCA Information tab, at least if youre using V1.21.0.78
After loading a VRCA into A.R.C. with the load VRCA button, you can extract the VRCA with the button right next to the load button, it normally extracts to a project (ittl spit out a assets and packages folder) that you can copy into a project that you created with VCC.
There is a option to extract to a Unitypackage, dont have much experience with it but the one time I used it it didnt work.
A.R.C. has several options included to try and unlock password but I dont have experience with these, I just go into the FX layer and look for the code.
Note 1: The data file youll find in your cache will be a generic file, youll have to add the .vrca yourself.
Note 2: To get the file out of your cache, do what xoxo´s said, also heard of people making python scripts to look to through search through the cache but none seem to be public. (probably not too hard to make bc the avi ids are intact in the asset bundles, open one in VSCode and search for "avtr" and see!)
Note 3: The ui layout may change with future updates of A.R.C.
Note 4: You do not need to log into A.R.C. or get a auth key!
Note 5: If youre not semi-experienced with unity, you wont be able to do this.
Note 6: You can get A.R.C. here in #repos, the repo is still marked as sars.: https://discord.gg/avatarrecovery, dont say that youre ripping without permission stuff because they dont seem to really allow it!
Note 6: Seems like I accidentaly activated some formatting stuff, too lazy to fix it!

It seems like this forum does not allow deleting, so looks like im just removing the content here.
Note: this wasnt a link to a asset.
