The logs show that Opus is just calling SHQueryRecycleBin which returns two numbers, the number of items in the Recycle Bin and their total size (SHQUERYBINFO).
That should not normally cause much disk access or take much time, but I guess could if there is a really, really large number of files in the Recycle Bin.
It could also indicate that the Recycle Bin is corrupted in some way, which happens sometimes. Deleting the hidden C:\$Recycler or $Recycle.Bin (or similar; it varies depending on the OS version which formatted the drive) folder and then telling Windows to repair the Recycle Bin the next time you delete something to it may fix things.
