Linux - Windows versions not cross compatible?

[bonzi9]

Just stumbled onto this tool to hide sensitive information.

For security reasons I want to use an air-gapped Linux machine to create the files with hidden data, which runs Linux Lite 5.4 from the live USB image. Using OpenStego v0.8.0 on both Windows and Linux.
Testing multiple possibilities to extract the data reliably I found that trying to extract the Linux-created hidden file on Windows 10 (build 10.0.19042.985, 20H2), always results in an error after multiple tries with different image files:

The (same) file can be created and extracted on Linux without issues:

Below is the Linux-created .png file with hidden data, the password is test123 and the embedded data is a file named "New File" which can be opened in a text editor to reveal "test 1 2 3 4 5 6 7 8 9 0".
