I'm not really familiar with python / renpy code, in my initial checks here's what I've found:Sorry guys... Inceton updated their protection, so I'm not able to decompile .rpyc files, and thus I cannot provide a patch.
Unfortunately, (as per my credits to xorxorrax on that post of mine) I was able to write my just because for v0.5.1 they used the same "renpy/script.py" they used for LustBound v0.4.1b for which xorxorrax provided , so at the time I just used the "renpy/script.py" provided by xorxorrax and it also worked for LustTheory v0.5.1
But as per LustTheory v0.5.2 it doesn't work anymore.

This time we need someone more skilled than me, I'm afraid...
I'm not sure if this is a global renpy thing, but between v5.0 and v5.2 of the game, in the \renpy\script.py folder I see random library added, and it appears the standard read_rpyc_data function is replaced with a new fuze_tea function, which is doing a bunch of weird byte manipulation.
So my thought is they modified the standard renpy compile/decompile function to their own custom format, which is why universal tools don't work. We have the function but is beyond me as well for the time it would take to make it trigger
