I have a similar issue with several of the win32 binaries in the IOLI crackmes. pddi output: https://pastebin.com/cqP6Y5uv

The IOLI crackmes are built against MinGW. I found that I can decompile the linux binaries without issue.

is this dev or main ?

https://github.com/rizinorg/book/raw/master/src/crackmes/ioli/IOLI-crackme.tar.gz

Cutter 2.3.2 running on Windows 11 Pro. Open bin-win32/crackme0x00.exe in Cutter with analysis (aaa) enabled. Open the main function in the decompiler view.

Note, Cutter 2.0.5 seems to work as expected.

@wargio: Were you able to reproduce the issue given that information?

[wargio]

yes, i was able to reproduce it, seems that something changed on rizin side and is returning an empty value. i'm not sure if it is worth spending time understanding what is wrong or just merging dev into master.
