Opus 11 freezes

Several times a day Opus 11 is freezing. When this happens I am unable to close it and have to restart Windows.
Have been using for years, and never a problem.
Could there be a connection with EaseUS ToDo Backup Workstation version 8 or 9? Problems with this image backup program started at the same time. However both have been in use a lond time.

They're usually caused by shell extensions.

Best place to start: [Crash, exit or high CPU when viewing certain directories)

(Unless you're getting the freezes when right-clicking, in which case this is a better starting point: [Crash, exit or high CPU when right-clicking certain files) )
