C++ Photoshop-API: Getting reference to Image takes 4min on a Windows PC

I do the following in a plugin:

    Auto_Desc result(false);

    Auto_Ref reference;

    OnErrorReturn(sPSActionReference->PutEnumerated(reference.get(), classDocument, typeOrdinal, enumTarget));
    OnErrorReturn(sPSActionControl->Get(&result, reference.get()));

This works well since a long time. But we have one specific Wind-PC at a customer, where the "Get"-call takes up to 4min.
It seems to me that the reason is a specific setting at that PC, but we have no idea what it could be.
Any idea how to solve this problem?

The settings of the PC:

Intel i7

Windows11, Version 2009

OS-Language: Dutch,

PS Version 25.2.0

This problem appears in PS 2024 and 2023, but not in older Versions
