Hello, in an asynchronous file server (ESPAsyncWebServer + AsyncTCP) the combination of Adafruit GFX and Adafruit ST7735 libraries interfere with the I2C connection of a keyboard. It doesn't matter if you use the SPIFFS_ImageReader library (fork of Adafruit_ImageReader) or render images in hexadecimal format, the keyboard has almost zero sensitivity.

I currently use ESP32WebServer with the same Adafruit libraries and Adafruit_ImageReader with no keyboard issues.
