Google Lock Samsung A5 2016: Unknown Error, Hard Reset & SD Card Data Recovery Help

Hello. Yesterday, all attempts (15 attempts) to unlock the screen with a pattern were used on my phone. After that, my phone reset, I had a hard reset and now I can't log in to my google account. I tried to log in to different accounts and each time I get the message "Unable to log in to the device due to unknown error. Try logging in to another account or again after 24 hours" In addition, I lost all photos from my SD card ... Please help and some advice if it can recover data from the SD card.

Remove the card from the phone and do not write anything on it. The data from the card is salvageable. As for the phone, go to the website where they will remove the frp lock.

I wonder if recovery from the memory card turned out to be easy.
My unpleasant experience with deleting an old phone and erasing data from this phone using the Google account function evokes interest in the condition of the above-mentioned card.
I don't know how and in what way Google brought another phone also assigned to the same Google account, brought it back to factory settings, and the card (128GB with over 80GB content) installed in the phone has nothing to recover. I didn't have a backup, exchanging words with Google makes no sense, and I'm tormented by a question. How can you erase 128GB in just a few dozen seconds? I would like to mention that the old phone that I deleted still appears on the account, and my phone appeared as "new" although it was assigned to the account from the day the Google account was created (several years).
I would be happy if my sadness turned out to be unnecessary due to my ignorance. But in a situation where I have to come to terms with what I cannot change, I would like to share my experience so that this doesn't happen to others.

It depends on the card configuration. By default, formatting the memory card takes a while, but it doesn't actually delete the data, it just creates a new file system. In this case, the data should be recoverable.

However, it is possible to configure the card in such a way that it serves as an extension of the phone's internal memory, which will also encrypt it. In this case, the encryption key is unavailable after restoring the phones to factory settings and the data cannot be recovered.

You can also encrypt the card yourself from the settings. Then, after resetting the phone, the data will also be unrecoverable.

Thank you very much for your answer.
I apologize for the long delay in continuing the topic that interests me.
After noticing the changes, I made an image of the card, and after removing the SIM, the phone is waiting for a "miracle".
I used the memory card in the phone as removable memory, saving backups and things that were important to me so that they would not burden the phone.
And I conclude that Google's interference has gone too far by changing the hardware configuration of my device. By transforming the value or meaning of a memory card by assigning it to a device by giving it a shared memory value.
So, my hope for recovery at home is gone. Since the operation of "google" is intuitive in the form of a reset code.
Let me joke that it is similar to "ransomware". Whose attack I will not miss.
Thank you very much for your interest and very valuable educational information.
