Samsung AC can't be turned off when using ESP32-S3

Version/revision of the library used

2.8.6

Describe the bug

I am using IRremoteESP8266 to control my Samsung AC.
If I use an ESP8266 it works well,
if I swap the ESP8266 with a ESP32-S3 it works well too but the "turn off" command stops working.

All commands works well but not the "turn off command".

To Reproduce

Just try to turn off the AC.

 // IRSender Begin
acir.begin();
acir.calibrate();
acir.stateReset();
acir.off();
acir.send();

What brand/model IR demodulator are you using?

Lolin IR shield, I tried with an IR diode (not VS1838b) and same result.

Can you capture the results using another the other ESP running IRrecvDumpV2c etc?

They should be the same, and produce the same output. The code base isn't any different

thanks for the answer, I appreciate it.

the result is different. off command works 10% of the time if any.
with same code.

I noticed that "when it does not work" it leaves my acir object or my AC in a state that is not able to receive other commands, even the one that works before sending the "breaking off command".

is there a command to completely reset the acir object?
does acir.begin()
resets all its states?
