I’m not an experienced user… but 3 months ago… last time I compiled my project it compiled and worked.
Today… I tried a compile and I got this error.
.pio\libdeps\esp32doit-devkit-v1\ESP Async WebServer\src/ESPAsyncWebServer.h:32:18: fatal error: WiFi.h: No such file or directory
I then did a pio upgrade in case but that didn’t fix it.
I have no idea why this has happened. I’ve not touched Platform io in 3 months nor changed the project but now I’m wondering what has happened?
Please show the full platformio.ini and the code you’re using.
Usually a library not recognizing a dependent library is an issue of not including the library header (aka doing #include <ESPAsyncWebServer.h> in the main cpp file) or having to use a different lib_ldf_mode setting.

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
lib_deps =
bodmer/TFT_eSPI@^2.3.59
contrem/arduino-timer@^2.2.0
iotappstory/IOTAppStory-ESP @ ^2.1.0-RC4

The thing is, the last time I compiled this it simply compiled and worked. Today it doesn’t.

Have you tried both of these suggestions?
As yet I’ve not tried to change any code to ‘solve it’ simply because the last time I pressed compile, it worked perfectly.
I’ve come back to the project after 3 months, and to my knowledge I’ve changed nothing during that time.
I was wondering if an update to PIO happened automatically while I wasn’t watching … but I’ve forced an update today to see if that somehow resolved the problem, which it didn’t.
I can’t offer any other input as to why today it just fails with that error.
