Research direction
The issue points to the custom deobfuscation py script, the database, and functions sub_423700 and sub_427fd4. Start by rerunning the script and opening the database, then compare stack-variable and basic-block analysis in those functions. Done means the failure is reproducible and the affected analysis behavior is corrected or documented with a minimal reproducer.
