Compilation error when including ESPAsyncWebServer

[notsolowki]

after updating to esp32 board 3.0.7, and using the latest async library i cannot compile successfully anymore it throws a bunch of errors. im using latest arduino ide. code was compiling until updating libraries and baords.

it appears the error went away when i downgraded fastled from 3.9.2 to 3.9.1.
