Bitlocker, SSD, data recovery

[FogelBoy]

Hello, there is a stock m.2 SSD Intel SSDPEKK256G7H (intel 600 series), which was provided along with the purchase of an HP ProBook 470 G5 laptop. After updating the laptop software and BIOS, I wanted to combine the divided volumes of this SSD (one of them was used to store backup data) in order to further optimize the SSD using Intel proprietary software.

The volume with the system was encrypted via bitlocker, but not completely, because Microsoft account was not logged in. In the windows settings, I clicked on the "decrypt" button, after which the decryption process began. In the device manager, the drive was loaded at 100% for a long time, the decryption slider reached about 1/3, and after a while the system hung and a BSOD window popped up describing critical prossed died (I suspect that this was caused by overheating of the SSD due to heavy load), the crash report freezes up to 0%, so I had to forcibly turn off the laptop. When rebooting, a window is shown that the OS is not installed on the selected drive, when rebooting again, the system booted normally, in the settings it was shown that the decryption process was continuing, but literally after 2 minutes the situation with the freeze occurred again, the whole process went in cycles. The bootable USB flash drive saw the encrypted system volume, but refused to enter it (the lock was hanging next to the icon); accordingly, it was not possible to copy the data using improvised methods. After several attempts to enter the system (before that, the system booted and worked for a minute or two), the system refused to boot, although the SSD is visible in the BIOS.

In general, the question is, is it possible to recover data from such an SSD with further decryption from BitLocker?

Generally -- NO -- as encryption will prevent the consumer-grade data recovery apps from finding anything useful.

There are commercial data recovery services that can bypass this to some degree -- but they are insanely expensive, as those I have checked out start at $1000 USD per physical drive.
