Thanks for the report,
Record Audio tool uses temporary folder to create output file and then copy file to the desired location.
What I see from the report:
"...
"Audio_recording_D253DC45-C162-4DF1-9F41-0499CBAE5152-38854-0003466D757925DE" couldn't be moved to "Desktop" because either the former doesn't exist, or the folder containing the latter doesn't exist.
..."
Could you please check existence of this file?
