Tethering funktioniert nicht mehr seit Update

"Since the last update, shooting with Tether no longer works, the program no longer connects to the Canon EOS R5"

Are you on Mac and did you update to Mac OS 14.2?  Something in Mac OS 14.2 broke connecting LR to devices via USB cable, and Adobe doesn't recommend installing 14.2:

See this article for options on rollback to 14.1:

If this doesn't apply to use, please do the menu command Help > System Info and copy/paste the entire output here.

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 (like this one has already been moved) if it helps you get responses.

Can you tell us which Adobe application you are using?
