lightroom classic 10.2 extremely slow

[signerro]

My lightroom classic 10.2 Version is now extremely slow. All actions such as opening catalogue, going from file to file, switching into development module are very very slow (>10 seconds...)

There is no working with this anymore!

System info is attached.

Thanks for your help!

In addition to what @Ian Lyons said, try checking these 3items:

1. Logitech plug-ins are known to cause slowness in Lightroom Classic, please disable them and see if the problem improves.
2. Make sure your virus checker is not scanning the Lightroom Classic executable (or the folder it is in), and is not scanning the folder your photos are in
3. Try reverting to LrC 10.1.1 https://helpx.adobe.com/download-install/using/install-previous-version.html
