I had the same problem (same MPLAB X IDE version 6.10). To resolve the issue you can clear the cache:

  • in MPLAB X, click Help > About
  • check and copy the 'Cache directory'
  • close MPLAB
  • open an explorer window and navigate to this directory
  • clear the whole 'Cache' folder
  • reopen MPLAB
  • projects should be loading fine now

But I need to do this every time before I startup MPLAB. So if anyone has a permanent solution, I'm listening...

MPLAB PICkit 3, MPLAB ICD 3 and several on-board debuggers fail to connect in MPLAB X IDE v6.10. When attempting to connect to these tools through selection in Project Properties, clicking Apply or OK will generate the error

“Failed to download firmware. Connection Failed”.

Fix: Install the MPLAB X IDE 6.10 patch. Do this by installing the 5 plugins suggested in the popup notification. These will enable MPLAB PICkit 3, MPLAB ICD 3, onboard debugging for certain eval boards and fix connectivity issues.

The 5 plugins are:

  • PICkit3 Tool [1.0 -> 1.1]

  • ICD3 Tool [1.0 -> 1.1]

  • PK3OB [1.0 -> 1.1]

  • PKOBSKDE [1.0 -> 1.1]

  • MPLABComm [1.1 -> 1.2]

Also find the Plugins by selecting Tools > Plugins > Updates.

I'm having the same problem and this is how I solved it. My native language is not English, so please forgive me if it's a bit awkward. thank you google

It is believed that this problem is due to some kind of glitch in the system for saving and recalling project files. Resolution:

  1. Procedure to exit MPLAB X-IDE v6.10
    1. Close all open files before ending MPLAB X-IDE v6.10.
    2. Close all projects in progress before ending MPLAB X-IDE v6.10.
  2. Procedure to start MPLAB X-IDE v6.10 anew
    1. MPLAB X-IDE v6.10 Start > File > Open Project > Go to ****.X from the top directory. Note: As soon as you start MPLAB X-IDE v6.10, if you open ****.X you will probably see "Loading...".
    2. If "Loading..." still appears after doing this, repeat from step 1 above.

I'm sure Microchip will fix this soon.
