error message

[cantaluppi.photo]

When I delete photos, the follwing error message appears: "?:0 attempt to index a nil value". I use Lightroom Classic CC (desctop version) and Windows 10. With Windos 7 I never hat that Problem. What can I do?

I think this error is more of an annoyance rather than anything fatal. You could try re-naming the prefs folder or re-installing in a new admin user account. See this link at the feedback forum.
