I had a NVMe drive that had one partition with a LUKS encrpyted Linux Mint 19 and another partition with Windows 10. Both were able to boot (I had grub were I could select Linux or Windows to boot). Then I re-installed Windows 10 on the second partition but this time I deleted the Win10 partition in the Windows installer and created a new one. At this point I think it created other partitions (I am not sure, maybe for UEFI boot or recovery). After that I was able to boot Windows and thought I could just repair grub and should be able to boot both systems.
Now when I load grub, I have the same old boot options but when I try to boot the LUKS encrypted Linux I get the error Encrypted LVM Boot fail (lvmetad not active) and volume group mint-vg not found.
When I boot from a live USB-Linux:

Device /dev/sda3 is not a valid LUKS device.
Is anything lost now? I heard of some LUKS crypto headers, are they deleted now? Any way I could recover it?

UPDATE: I forgot to mention that the system did a firmware/BIOS update after rebooting.
sdais your USB drive. To see partitions, usefdisk -l.
