I had exactly the same issue with an esp32 Wroom-32D and the Arduino IDE 2.3.2. I have also tried other AsyncWebServer libraries with the same error.

[khawajamechatronics]

I am facing same issue.

My solution：
#define mbedtls_md5_starts_ret mbedtls_md5_starts
#define mbedtls_md5_update_ret mbedtls_md5_update
#define mbedtls_md5_finish_ret mbedtls_md5_finish
#define ets_printf log_e

Without getting error with other esp32 boards I did do following edit in the library files
Compilation of my source code are error free for ESP32 DEV, ESP32 C3 DEV and ESP32 S3 DEV boards

OK, so I had the same problem. Started to modify a program I last touched a year or two ago and it wouldn't compile after I updated all my libraries and board definitions.

In addition to the changes listed by ednieuw above, I also changed in
~/libraries/ESPAsyncWebServer/src/AsyncWebSocket.cpp

line 323 if(_sent == _len){cpp -> if(_sent == _len){

Don't know how that "cpp" crept in there.
