Could you share your Arduino.INO file to reproduce this issue?

I was able to build and upload my project last night still, today I get a similar error:

I updated the Espressif 32 platform to 1.11.1 to try and see if it will resolve the problem, but still the same error.

I presume something updated in the background on the platformio side, no changes were made to the code yet.

I checked the library.json, library.properties or module.json of my lib folder, none was updated for weeks. I even tried building and older working snapshot. No luck. I also tried with a clean main.cpp with empty setup and loop functions. The error persists.

After checking all my libraries I found some library.json files of Rhys Weatherley's libraries were not JSON compliant. A comma "," was missing after the "keywords" item for some of his libraries.

Just strange that the library.json files did not cause issues prior to today.

I hope this will help somebody in the future getting the same error.
