I’m having problems with two scripts that crash MB when characterizing.

the first script is supposed to run on a skeleton that has animation.
first it does a bunch of things to the skeleton and then characterize it in a Tpose.
it crashes MB if I characterize. if i comment the characterize function everything works fine.
I can run each part seperatly, so do all the tpose etc.. first, save the file, open it again and then run characterize. But I have to save it before characterizing otherwise it’ll crash.

I copied the characterize part from one of the scripts that come with MB.
the debugger looks like it runs the whole thing without problems. but it still crashes MB.

Any ideas?

the other script is even weirder.
it’s for batching character rigs and runs 3 scripts. one for batching (openclose files etc...). that batching script imports and runs a characterize script and a controlrig script after.

each script works if I run them seperatly, and i can batch the characterizing script. the crash occurs when i also run the controlrig script. It does work once in while, but 95% of the time MB crashes.
The debugger stops in the characterizing function in the characterizing script.

I know it’s a tricky question since i can’t really post all of that here, but i’m hoping that someone might have a clue what’s happening.

Thanks in advance.
