Normally the software works great, but recently it has started freezing, moving very slowly, cursor flickering. Should I uninstall and reinstall it? If so, will I lose my files? They no longer show up in the Local Files window on the left. I have to click on File and Open every time I want to open a file. I'm afraid that they could disappear completely.

Yes, uninstalling and reinstalling the software might resolve the issues. Typically, reinstalling won’t delete your files, but it’s a good idea to back them up first to be safe. If your files aren’t showing up in the Local Files window, try checking the file paths or locations within the software settings
