I have just seen the same blog and was about to link it

Don't know how much their Portable Pro costs but it might be more than a new laptop..., on the other hand, it's the data you want rather than just a working laptop.
It looks quite complicated.
It could be worth trying Ease US data recovery. There is an offline version. I've seen it mentioned as an option on a few online posts. I used it once when my external back drive failed before I restored my data to a new install..............It recovered everything. Whether it works with the Optane drive I don't know but it's worth a try - I think there's a free version but I did get the paid-for version at the time as it wasn't that expensive and had a lifetime licence. About £30 I think?
So for that you'd need the Optane Drive back in the computer, and boot the EaseUS recovery from USB
This is from AI
"To recover data from an Optane drive using EaseUS offline, you'll need to create a bootable USB drive with EaseUS Data Recovery Wizard WinPE Edition. Then, boot your computer from this USB and use the software to scan the Optane drive for recoverable data.
Here's a more detailed breakdown:
1. Prepare the Bootable USB:
Download and install EaseUS Data Recovery Wizard WinPE Edition.
Create a bootable USB drive using the WinPE Edition software.
2. Boot from the USB:
Connect the bootable USB to your computer.
Restart your computer and boot from the USB drive.
3. Use EaseUS to Recover Data:
EaseUS Data Recovery Wizard will launch.
Select the Optane drive you want to recover from.
Start a scan for lost data.
Preview the recovered files and choose which ones you want to save.
Recover the files to a safe location on another drive. "
