When moving folders within the same drive, the data gets moved successfully but TeraCopy throws an error:

After a lot of testing, it seems as though the folders are being moved before TeraCopy even starts up, so the source folders are no longer where TC expects them to be, thus the error. Note: this only seems to happen with folders. Moving individual files causes no error.
I'm on the latest versions of both XYplorer (20.9) and TeraCopy (3.26).
Any ideas?
