PLEASE HELP! Trezor Catastrophe

I’ve used Trezor for years, they’re great. I was helping my in-laws move their crypto (sadly they divorced and wanted me to separate their crypto) and fear I have made a TERRIBLE mistake.. I set up my father in laws new Trezor and sent his half of crypto from my mother in laws wallet. Success..

I realized I did not get the seed words from the Trezor, (I think it got disconnected from the lap top during initial setup) and I had to secure the USB connection and continue setup. What I didn’t realize at the time was I ‘believe’ that was my one and only shot to collect my seed words. Not knowing that I continued the setup with a PIN and sent the funds. They showed up but I realized I did not have ANY of his seed words and if he lost this thing or it got stolen he would be screwed..

So I sent the funds back to mother in laws Trezor, successfully.

I saved the address to the wallets and WIPED my empty father in laws Trezor and successfully set it up, (this time collecting all seed words).

I SENT THE CRYPTO to his old address that was wiped and I don’t have the seed words to!! I was hesitant to even get involved, they are older and not technology savvy, but I got them into the crypto space years and wanted to help them with this separation. This was NOT a small amount of Crypto and has become a strain on the family. I had the best intentions..

I reached out to Trezor support but they have not gotten back to me.

Does anyone have any advice please?!
