Thanks for reporting this problem. Unfortunately this is yet another bug in the Java provided file dialog on Windows 10/11.

This means it is a bug in the Java run-time library, not a problem of Jadx - there is nothing we can do in Jadx to fix this problem. The latest version contains a workaround for a different file dialog bug on Windows 10/11, but I don't think that it will have an impact on this problem. Anyway, please try Jadx 1.4.4.

Possible workarounds:

• enable Preferences -> Other -> Use alternative file dialog option, this will use another file open dialog implementation.
• use jadx bundle with included JRE, maybe issue is fixed in latest java verions
• try jadx latest unstable build
