Can't open files in utoc/ucas archieves | Subliminal | ue 5.7.3.0

[lynrayy]

I am exploring subliminal (ue 5.7) files:

This is what fmodel can see:

This is the issues when trying to open model:

[ERR] CUE4Parse.UE4.Exceptions.ParserException: Package has unversioned properties but mapping file is missing, can't serialize
   at CUE4Parse.UE4.Assets.AbstractUePackage.get_CanDeserialize()`  

 An unhandled System.ArgumentNullException occurred: Value cannot be null. (Parameter 'key')  

What should i do, and what is so called utoc/ucas? Never seen this before.

Ok thank you!
Used this tool: https://github.com/trumank/jmap
It is very easy, dump game's RAM (literally in windows task manager), create .usmap and specify it in fmodel!

The result:
