Error msg: "Unable to watch for the changes in this large workspace. Please follow the instructions link..."

Describe the problem

Small Arduino script. I'm watching the Serial Output over time checking for script errors.
Arduino library has 2499 files only.
IDE boards include ESP32 and ESP8266.

Error message only seems to appear after longer runtimes:

Unable to watch for the changes in this large workspace. Please follow the instructions link to resolve this issue.

Instructions link in error message sends me here:

Running Windows Task Manager shows a steady increase in memory usage running only one pretty simple script on an Adafruit ESP32 Feather.

Just got this after updating to IDE 2.1.0, and then installing the 'Arduino Mbed OS Nano Boards' library from the Library Manager.
