Something interally went wrong when accessing a JSON file that may not exist.

It also seems to me that you installed PlatformIO globally if this is in the backtrace? That’s not recommended.

I’d suggest to

  • rm -rf /home/kostas/.platformio/packages
  • rm -rf /home/kostas/.platformio/platforms
  • rm -rf /home/kostas/.platformio/.cache

to force PlatformIO to redownload at least all packages and platforms if some got corrupted.
