[Koha] Activating preference "ILLModule" leads to error 500 in Koha 24.05

Hi When in Koha 24.05 trying to activate the system preference "ILLModule" it leads to error 500 when clicking Koha staff client menu "ILL requests" or clicking menu "About > System information". In file "/var/log/koha/<instancename>/plack-error.log" it says: Can't call method "GetPlugins" on an undefined value at /usr/share/koha/lib/Koha/ILL/Request/Config.pm line 118. This behavior appears in Koha 24.05.01 and 24.05.05 (but it works as expedted in 24.11) . Does anyone know the solution of this problem?
