Hi there! First of all, thanks for making this script. It's crucial for debugging purposes.

Long story short, I've install python, all other listed dependencies, compiled CryptoMobile. All looks good, I can see GUI but still can't decode anything. Not sure maybe my pyshark (latest) broken? or simply script needs some modification to work with latest dependencies versions? Here is what I see in the python terminal output:

2023-08-02 14:48:53,777 - INFO - waiting for pcap filtered by ngap protocol,0 seconds passed.

2023-08-02 14:48:54,778 - INFO - waiting for pcap filtered by ngap protocol,1 seconds passed.

2023-08-02 14:48:54,778 - INFO - filter pcap by ngap protocol finished, now start dectypting!
