MobSF Unhandled Exception, System.InvalidOperationException while analyzing .appx file

Question

I've implemented MobSF for security testing of mobile applications including android and windows mobile applications. It's working fine with .apk files but I'm facing an issue while analyzing .appx files.

I have run the command setup.py in command prompt also and installed Binskim and other tools also like BinScope but it keeps giving me error. Please look at the above error and help me out of it so I can go for further.

Attaching two screenshots also for the reference.

Hope I've explained my problem. Thanks in advance.
