Bitcoin Theft from Trezor Hardware Wallet

Hi all, would really appreciate some assistance on this. Facts set out below. And I understand I obviously made a mistake somewhere; however, I just can't think of anything credible.

Background:

I had approximately 0.542 BTC (€13,500 approx) on a Trezor One Hardware Wallet. The public key for this wallet is:

zpub6qxBuMaaZyKbP9c9N7mYZrSpGysvnEeerv98HF5QKjBGQBukhEQuK6z3nZ2ju9Z39mwvjX4U3C3Uc56VxCFA9ZYoKVUALX8t4x9ubgTnxg3

On 08 June 2023, I connected my Trezor to notice that the wallet was empty.

I then noticed that there was a transaction for the entire contents of the wallet made on 06 June 2023 at 1951, whereby approx. 0.5418 BTC was sent to another address. I did not make this transaction, and had not used my Trezor device in more than a few days.

The Transaction ID for this is:

ad9bba21535ab52361b8550812cc1a08af6afbc16ad0e05e6a6118d4de8b28f4

The wallet it moved to is:

Other Info

I am certain that my seed phrases are secure and have not been accessed by anyone.

I have my Trezor Hardware Wallet, which has a pin, so am quite sure nobody accessed it.

When writing down my seed phrases initially, I did not take a picture, did not type them into my laptop, and simply wrapped them up and put them away.

I have never typed my seed phrase into my laptop.

There were other funds behind a passphrase, which were not accessed. (I have subsequently moved these to another device).

I was at all times using the Trezor Suite App on my laptop. My firmware version is 11.1.2 (there is I believe an upgrade due).
