Model decompile problems

So long story short, lately mdldecompiler is being a bigger headache than usual. Certain models when I try to decompile them just spit out a blank qc and a vta file. Even some models that I have successfully decompiled in the past are giving me this error and I don’t know what to do. Am I forgetting something or did the old decompiler finally just stop working?
Supposed fixes I have tried:
replacing IDST1/0 with IDST,
using the hacked version

Have you tried deleting the sdk/bin/ep1/bin folder and verifying the cache? That fixed it when I had that problem.

Place it in the sourcesdkbase/bin folder see if it helps

Although that may have helped a little, the qc now appears to have all the flex information.

Nothing.
