Hey Samandkit,
If you're having an issue with the performance of a particular app, we'd suggest making sure that both your Mac and Lightroom Classic are fully updated. Your Mac should be running the latest version of macOS Ventura, which is 13.0.1.
If you continue to have issues afterward specific to Lightroom Classic, you may want to uninstall the app and reinstall it. If all else fails, we'd suggest reaching out to the app developer for further assistance:. These steps can help with that:
Contact the developer of a macOS app
1. Open the App Store on your Mac.
2. Click the sign-in button
or your photo.
3. A list of apps appears. Click the app that you want. If you can't find the app, use the search bar.
4. The app's product page appears. Click Support or App Support. If you don't see Support or App Support, make sure that you're signed in with the correct Apple ID.

This information is outlined in more detail here: How to contact an app developer - Apple Support
We hope this helps out.
Take care!
