x11-fm/doublecmd plugins didn't work

I am using x11-fm/doublecmd for many years but whenever I tried some 
plugins (Network o Archives) it does not work.

Now I tried for example FTP plugin. In the top menu clicked on "Network" 
/ "Network Connect...", new tab with title "vfs:" where created. There I 
see 2 items:
FTP
Windows Network

Clicked on FTP:

Cannot load WFX module /usr/local/share/doublecmd/plugins/wfx/ftp/ftp.wfx

Clicked on Windows Network

Cannot load WFX module 
/usr/local/share/doublecmd/plugins/wfx/samba/samba.wfx

Both files are there:

% ll /usr/local/share/doublecmd/plugins/wfx/ftp/ftp.wfx 
/usr/local/share/doublecmd/plugins/wfx/samba/samba.wfx 
 

.rw-r--r-- root wheel 3.4 MB Mon Sep  2 14:11:35 2024 
/usr/local/share/doublecmd/plugins/wfx/ftp/ftp.wfx
.rw-r--r-- root wheel 1.2 MB Mon Sep  2 14:11:35 2024 
/usr/local/share/doublecmd/plugins/wfx/samba/samba.wfx

I also tried to run doublecmd from console to see some error output, but 
only these 3 lines where printed when I clicked on FTP of Windows Network

Creating TVfsFileSource
Creating TWfxPluginFileSource
Destroying TWfxPluginFileSource when refcount=1

Are there somebody with working plugins setup in Double Commander?

I am really curious what's wrong with my setup for all these years.

Kind regards
