I opened the Default preset, added a few nodes to it, clicked "Save", named it "Delays", chose my Documents folder, hit Enter, and it produced an error shown in the images. However, when I stopped the scheme and rebuilt it, it opened the plugin and I can load the preset I saved. That is, it creates an error only when saving a preset, but if you reopen the project, you can load and play the preset you saved without an error.
