It is possible the error was a one-time event. Try the operation
again.
There may be a problem programming in general. As a test, Run without
Debugging and program the target with the simplest application possible (for example, a
program to blink an LED). If the program will not run, then you know that something is
wrong with the target setup.
It is possible that the target device has been damaged in some way
(for example, over current). Development environments are notoriously hostile to
components. Consider trying another target board. Microchip offers Curiosity and
Curiosity nano boards to support many of its microcontrollers. Consider using one of
these applications, which are known to work, to verify correct MPLAB®PICkit® Basic In-Circuit Debugger functionality.
Review debugger setup to ensure proper application setup. For more
information, see the “Connections” and “Operation” sections.
Your program speed may be set too high
for your circuit. In the command palette, enter MPLAB: Edit project properties
(JSON). select the PICkit Basic
category, Program Options option category. Next to Program Speed select a
slower speed from the drop-down menu. The default is Normal.
There may be certain situations where the debugger is not operating properly and
firmware may need to be downloaded or the debugger needs to be reprogrammed. See the
following sections to determine additional actions.
