The logs are showing two errors, a file output error with the file path and the CPE file issue you referenced.
The app is not able to open that export location that you have currently set, double check that it exists. You can refresh the location in the Preferences Panel or choose a new location to write out to.
The team is working on the CPE issue that some users have shared. Several instances were due to an issue with the file path being inaccessible for the temp file to be written.
Try resetting the file path and the directories and run the export again.
If that doesn’t work, send the updated logs to the support team for further review, help@topazlabs.com
