Error installing ACSM Input plugin (AttributeError: module 'calibre_plugins.deacsm.prefs' has no attribute 'DeACSM_Prefs') about acsm-calibre-plugin

[Sebadier]

I had the same problem and it was related to the wrong openssl version installed by Homebrew on MacOS Sonoma
If you have homebrew installed you can unlink openssl of homebrew.

brew unlink openssl@3

A very similar error on OSX (Sonoma) + Calibre 7.6.0: it complains about ACSMInput_Prefs instead. This happens with the latest release and with the current master.
