LrC freezes when copying develop settings

[Helge28363393r1hn]

I've been using LrC on my PC for many years without serious problems but actually it freezes when using the "copy develop settings" option (Ctrl+Shift+C). No reaction to any further mouse clicks, menues are all grey. The only possibility to go ahead is "Esc" but then the develop settings are not copied and cannot be pasted to other photos.

LrC Version 12.1

Windows 10, latest version.

Try resetting your Lightroom preferences:

Quit Lightroom Classic.
macOS: Press and hold the Shift + Option keys.
Windows: Press and hold the Shift + Alt keys.
While holding down the keys, launch Lightroom Classic.
When asked, select "Yes".

I have no idea how to do this, it makes no sense to me....

In recent versions of Lightroom Classic, you can reset the preferences from the Preferences dialog.

Go to Edit menu > Preferences (Lightroom menu > Preferences on a Mac).

In the General tab, mouse over the Reset all warning dialogs button, then press the Alt key (Option key on a Mac).

Click the Reset all preferences and relaunch button that appears.

Will this delete anything from my library? I use external HD to store all photos (I have 2 6 TB external drives)

It won't affect your work at all.

The only thing that gets deleted is the Preferences file, which will be recreated when LrC relaunches.

Thank you! I will try this!
