I can't think of a reason, the lib really doesn't do anything special.
Although, why are you defining sds011Serial? By default, all the hardware serial objects are already defined as Serial, Serial1 and Serial2.

i did this because in the esp32 example in the main.cpp it is also done like this.
I tried to take the example and rewrite it for arduino IDE. actually i did not really write anything.... just copied the code together since it looked quite straight-forward.

Oh, you're right. I wonder why I did it...
You're using the latest Arduino core, right? Because Platformio is lagging a few version behind and Hardware serial has been completely refactored.

yes i am using the latest version - i try to stay up do date :)
is this maybe correlated to my problem?

I changed the sketch as i could not identify any other dealbreakers in the library itself.... unfortunatly no change... :(
#include <SDS011.h>
SDS011 sds011;
void setup() {
Serial.begin(115200);
sds011.setup(&Serial1, 15, 2); // Rx on GPIO14; Tx on GPIO12
sds011.onData([](float pm25Value, float pm10Value) {
Serial.println("Data arrived: PM2.5 = " + String(pm25Value, 1) + " μg/m³; PM10 = " + String(pm10Value, 1) + " μg/m³");
});
sds011.onResponse([](uint8_t command, uint8_t set, uint8_t result) {
Serial.println("Response to command 0x" + String(command, HEX) + " received: 0x" + String(result, HEX));
});
sds011.onError([](int8_t error) {
Serial.println("Error occurred: 0x" + String(error, HEX));
});
sds011.setWorkingPeriod(1);
Serial.println("Data should appear on the default serial port in less than a minute");
}
void loop() {
sds011.loop();
}

And you are sure the pins you assign are correct? Because your comment gives the gpio numbers but in the code you use other numbers.
Are you using a premade board or your own design?

i am using an esp32 from az-delivery. - yes i am aware of the different gpio numbers i am using. the wiring works. with different libraries i can measure without any problem... but i did not find any non-blocking libraries that work - therefor yours is so interesting to me.

I'll start my setup but I can only test with an esp8266. I only got one device and it is soldered.
Now, there should be no difference between 32 and 8266.
from sds011.
this would be so great... in case i can help by ordering a device for you i will gladly do that and i am keen on testing whatever you find out :)
thank you so much!
from sds011.
i am terribly sorry...
i just rewired everything again after another library failed too... and apparently one of the pins was loose and kind of fiddly... i fixed that and it started working... sorry if this occupied your time.

No worries. I'm happy it works.
