Additional context

I am using the ese.py and structure.py file from this repo to parse Windows srum.dat file and getting the above error when running on Windows 11, 25H2. I've also tried on older Windows 10 and it seems to be working.

@wxt thanks for reporting!
can you provide an example code in order to trigger the issue?
which version of impacket seems affected? as you're reporting 0.11 but then you mention repo code.
Also consider that python 3.6.9 is not supported.

thank you
