CSGO items no longer in inventory.

Weird circumstance, but I only just downloaded and booted CS2 for the first time today. Havent touched CS since like 2017. I had some skins in CSGO, nothing crazy, all low value trashy. However, I cannot find my CSGO inventory on steam, and none of the skins transferred over to CS2. I have got literally 0 skins in my inventory.

This was not me getting hijacked/hacked, my trade history has nothing new in it at all since I traded a few skins back in 2016. My CS2 inventory is empty barring the music packs and badges I got from booting the first time today.

Where did my CSGO inventory go? How can I access those items again?

Any help much appreciated.
