After our R&D checking on this matter, it seems it is a macOS bug and it was fixed in 12.4.
Hence, we recommend all the users upgrade to the latest macOS version (also due to the security vulnerabilities).
Thank you.

I get a similar experience on my MacBook seems like its a core file from f-secure's capricorn signature engine.
You can find it using:
sudo find / -name aesbx.dylib 2>&1 | grep -v "Operation not permitted"
---- results on my machine
/System/Volumes/Data/Library/F-Secure/guts2-datadir/capricorn-macos-2/1653629011/aesbx.dylib
/System/Volumes/Data/Library/F-Secure/fssp/var/databases/capricorn-macos.1653629011/aesbx.dylib
However there seems to be a bug as the FileVault never manages to complete verification of the file
@Firmy can you confirm that this file should not be harmful?
