As in the Title Plustek 2420+ with Native Interface and twain works fine in 6.1.2 but throws an error in newer versions of NAPS2. If anyone want to reproduce this error, you have to disable driver signature check in Windows to install the driver/software.

That error indicates the TWAIN process crashed. You can try checking the Windows Event Viewer under Application and see if it has any relevant errors.
