CS:GO Inventory Replaced with Desert Eagles

I recently discovered that my inventory, valued at just over ₺30,000, has been replaced with desert eagle items, including a "slightly worn stattrak bowie knife lore," "brand new huntsman autotronic," "mission-used shadow daggers secret city," and "slightly worn usp-s corpse confirmed." Yes, each of my 126 items has been swapped out with only Desert Eagle items now (as seen in the attachment I provided).

I've checked my trade history, and there's nothing suspicious. I've also reviewed the recent sales in the market history, and again, there's nothing unusual there. What's even more bizarre is that I'm currently in a 15-day trade block due to reinstalling Steam Guard on my new phone. So, there's a bit of an intriguing situation from every angle.

Now, let's entertain the idea further: could it be that there's a security vulnerability in Valve's popular game, Counter-Strike 2, allowing malicious software developed by ill-intentioned individuals to manipulate inventory items? I apologize, but the ongoing development of the Counter-Strike 2 update, raises various concerns. But setting all that aside, let's focus on the inventory issue. I've been a CS player since 2016, and I demand the return of my items valued at over ₺30,000. Please, let the relevant departments address this matter. Thank you.
