(1) If you are sure BitLocker is off & all your drives are decrypted - fine.
(2)
(a) Your SetupDiagResults.log says: "RegisteredAV = Bitdefender Antivirus". So, go to the following site & uninstall it. After all your problems are gone, you may reinstall BitDefender, if you still want it...

(b) Afterward, ensure Windows Defender has automatically reactivated & is your real-time antivirus. That can be seen at "START, Settings, Update & Security, Windows Security, Open Windows Security, Virus & Threat Protection, Manage Settings button (under Virus & Threat Protection Settings)"...
(c) Once BitDefender is gone, try those two BCDEdit commands again at an Admin Command Prompt...
BCDEdit /Enum {fwbootmgr} <<<Show Firmware Boot Manager
BCDEdit <<<Show Windows Boot Manager & Boot Loader
Use Ctrl-A & Ctrl-C to show us the results.
(3) As Ramesh points out, it looks like neither EFI on Disk 0 nor on Disk 1 is your true EFI. You seem to have a 3rd EFI. Ramesh sees "HarddiskVolume6" mentioned in a log. I see "... 8" mentioned in your MSInfo32...
"Oppstartsenhet \Device\HarddiskVolume8"
The HarddiskVolume number is counting partitions starting with the 1st partition on Disk 0. Not all partitions show up in Disk Management, so DiskPart is needed.
(a) Unplug all your external hard drives.
(b) Let's see...
DiskPart <<<Enter DiskPart
List Vol <<<List the volumes & letters
List Disk <<<List the disks
Select Disk 0 <<<Focus on Disk 0
List Part <<<List its partitions
Select Disk 1 <<<Focus on Disk 1
List Part <<<List its partitions
== Continue to select & list each disk that showed in List Disk ==
Exit <<<Exit DiskPart
