SLOW DOWN. DO you still have access to your account, yes or no.

Do these 5 steps to ensure no one on your account.
1. Scan for malware https://www.malwarebytes.com/

2. Deauthorize all other devices https://psteamproxy.yuanyoumao.com/twofactor/manage

3. Change passwords from a clean computer.

4. Generate new backup codes, and if using Steam mobile app, redo that as well by removing it from account, and readd it back on your account for mobile device.

Yes, go to Steam help page > click on games, software, etc button > search your missing games, click NOT in my library, click RESTORE, and game restored back on your account.

The "permanently delete my game" DOES NOT delete game license from your account, it only HIDES it from YOU that it.

He didn't deleted anything, it's merely an advanced "hide" option.

To restore missing game/s:

• https://psteamhelp.yuanyoumao.com/en/wizard/HelpWithGame
  
• Enter name of the game in search bar,
  
• Click on game,
  
• Click on "it's not in my library",
  
• "Restore removed package".

No you don’t lose it I think

but when i click the game, only 'purchase' button there

no restore button there

Steam SUPPORT / HELP page. NOT THE STORE.
https://psteamhelp.yuanyoumao.com/en/wizard/HelpWithGame

Search for said game IN THE HELP page, and select the game, click on NOT in library, and it will tell you if you have EVER had bought, or redeemed it, it will show you RESTORE option, and all have to do is restore that it.

What game are you having trouble with?

If you use MULTIPLE accounts, you need to KNOW which account you have BOUGHT said item for, and if can't remember go visit your emails, or even purchase history.

If need video to show you how it works, please watch.

a small button saying "remove" should be below each game in your cart
