Is it possible to recover all the games I have purchased on Xbox and transfer them to PC?

A few months ago, my Microsoft account got hacked and its email was changed, so I can’t access it anymore. On that account, I had tons of games purchased that I want to download and play on my new PC. Would it be possible to transfer the game library? Not the whole Xbox profile though, just the purchases.

Nothing is transferable between accounts. Even if it were possible (which its not) youd still have to have access to the original account.

The only way of recovering your purchases is recovering the account.

You can't transfer the games themselves across, no. If any of them are Play Anywhere games, then you can download and install the PC version for free...any others and you will need to purchase them again. As to the game saves, a lot of games have cross-platform saves so it may be possible to continue your progress on the PC version

It's not possible to transfer ownership of games between accounts. You would also need to purchase the PC version in order to play on the PC. The Xbox version will only work on the Xbox.

I've looked through every reference already for all purchase history on both the Xbox and online. Nothing. This is the only account I have ever used or bought anything on so that isn't possible. I never licensed transferred with anyone, or recovered someone
else's profile who owned it. I'm stumped.

Not without purchasing them on your own account. Games are tied to the account that purchased them and it's not possible to transfer digital ownership.
