HI @Methos777, thanks for reaching out and welcome to the Lightroom Community Forum! Let’s try a few things to see if we can get those presets working again.
Force Quit Lightroom: Make sure Lightroom is completely closed.
Update Lightroom: Ensure that Lightroom is updated to the latest version.
Check Disk Space: Ensure that there is sufficient disk space on your local drive, as a lack of space can cause loading issues.
