How do I decrypt a previously encrypted SD memory?

[mohrestan]

Hello

I made a fatal mistake

I encrypted my mobile SD four years ago.
The phone had a problem a few days ago and I did a factory reset without decoding. The decryption key is no longer active in the settings!
My camera folder contains over 5,000 photos and videos up to 40 GB in size. These are family memories. I recorded all the moments of my son growing up with this mobile phone.
Now I see the files, they are the right size, but because they are encrypted, they no longer run on my phone and laptop.

My phone is Samsung Note 8 and I encrypted the memory with the same phone.

what's the solution?
