WL 9.5.40 crashes when using Resampler in WatchFolder

When using Resampler in Custom Plugin Chain on WatchFolder, WL 9.5.40 crashes.
The crash has occurred since WL9.0.
Conditions of WatchFolder:

  1. WaveLab Pro 9.5.40 x64 on Windows 7 SP1 x64
  2. Using Resampler in Custom Plugin Chain
  3. XML Input
  4. Runs in the background

If you run the batch processor, independently from the watch folder, does the same thing happen?

It happens only when batch runs on the watch folder in the background.
When runs independently from the watch folder or starts the watch folder in WL session, Resampler completes normally.
