BSOD on new SSD

Hello all,
I've recently installed new SSD to my pc. connected it via SATA to my mobo. switched in bios to AHCI, and installed fresh OS on it.. I was told that way it will automaticly will install the AHCI Drivers. anyhow the Drives are listed as SCSI devices, after some failures of changing it, i gave up since the benchmarks are really good.
That was the background. Since the installation i've got 2 times BSOD with the following error:
IRQL GT ZERO AT SYSTEM SERVICE

is it related?
I'll attach the debug zip.
Thanks for the helpers

Hi afikbar.

fffff880`074ea838 fffff880`03222a9aUnable to load image \??\C:\Program Files\Common Files\Bitdefender\Bitdefender Firewall\bdfwfpf.sys, Win32 error 0n2

*** ERROR: Module load completed but symbols could not be loaded for bdfwfpf.sys

Can you uninstall BitDefender, at least as a test?
