synchronization does not work

[nieta22222213z3ce]

If I want to synchronize 2 photos, the computer is fixed and I can only continue if I cut the escape in key. Does anyone know how to fix this?

Please share some more details, otherwise it's impossible to help.

- Your OS

- The exact version (numbers, not latest or alike) of your Lightroom Classic

- Are there any error messages?

- Describe in more details what exactly you are trying to do. Synchronizing metadata or developments, and which of the multiple available ways?
