Hello, the launch of paragon hard disk manager (16.5) is very long. More than 10 minutes and each new click freezes the application for a few minutes. Once the backup has started, no particular worries. I don't know what the delays are due to. No cpu or memory occupation.
Hello and welcome to the forums!
Usually this happens when there are many disks connected to your computer, using slow interface like USB 2.0, and containing file system errors on the partitions.
Disconnecting such disks prior to HDM launch resolves the issue in most cases.
Hope this helps!
