Error The disk image could not be created because the file is busy

DropDMG

DropDMG stopped making disk images for me and instead reports this error:

"Error The disk image could not be created because the file is busy.

It may help to disable anti-virus software or disk scanning utilities such as Micromat Checkmate and the DrivePulse component of Drive Genius."

MacOS: macOS 11.0.1 (20B28)
DropDMG: DropDMG 3.6

I’m not running anti-virus software or Drive Genius.

What are the source and destination folders for these disk images? Have you tried restarting your Mac?
