Yes, my newly installed PlatformIO was using “Espressif 8266 @ 4.2.1” which appears to be incompatible with FastLED when combined with WiFi.

SOLUTION:

In VSCode…

PlatformIO > PIO Home > Platforms > Embedded > Scroll to Espressif 8266 and click…
Dropdown select version 2.6.3… Click install
You will now have 2 versions of Espressif 8266 listed under PIO Home > Platforms > Installed

Now go to your project’s platformio.ini file and change
platform = espressif8266
to
platform = espressif8266@2.6.3

Things work fine again.

If that is the case, and you’ve verified that it does work with the latest ESP8266 core version in the Arduino IDE, then please file an issue in https://github.com/platformio/platform-espressif8266/issues so that this can be resolved properly instead of downgrading to ancient versions.
