Can you attach your .pcap file and .pdml file?
In my case all work well:

Maybe you need to update tshark or temporaly remove this option for troubleshooting
tshark: -o flag "nas-5gs.null_decipher: TRUE" specifies unknown preference

Update wireshark tshark from 2.6 to 3.6. project work fine now. 🙏 Thanks

The cause of the error is that in the Windows version (where this was initially implemented) the tshark version is inferred from the folder name. In Linux, since "portable" Wireshar does not exist and one just uses an installed one, that is not possible. Older tshark versions do not support nas-5gs.null_decipher, so when the parameter is blindly used based on the OS parameter, tshark complains. It should be possible to add a pre-check of the tshark version when OS is used by extending the check here to first call Tshark to output the version number, read it and fill in a variable with it.
