Thanks for reaching out. Could you tell us a bit more about what’s going on? It would be helpful to know which version number of Lightroom you’re using, whether you’re seeing any error messages, and when exactly the slowness happens — like if it’s during startup or after using a specific tool.
Looking forward to your reply so we can help you out!
Best, Alek
