Lightroom picture does not show on developed mode. visible in the list, but unable to edit.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Do you have a subscription to the Photography Plan and are you logged into your account? If Lightroom Classic cannot find an active subscription, it goes into 'Expired Mode'. In that mode you can still use it, but the Develop module and the Map module are disabled.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
