Adafruit bootloader : 'Scheduler does not name a type'

Hello,
I usually use your TaskScheduler on Arduino with great pleasure. Thanks for that.
Today I flashed an Adafruit Feather bootloader on a nrf52840 custom board, it works fine. When I import the Scheduler library and want to use it, I get an error that appears and I don't know why. Do you have an idea ? It seems to me that nrf52 is supported.
Code Snippet :
#include <TaskScheduler.h>
#include <Arduino.h>
#include <Adafruit_TinyUSB.h>
Scheduler runner;
Task t1(100, TASK_FOREVER, &ble_task);
Task t2(1000, TASK_FOREVER, &battery_monitoring_task);
void setup()
{
runner.addTask(t1);
runner.addTask(t2);
t1.enable();
t2.enable();
}
void loop()
{
runner.execute();
}
And the error I get is 'Scheduler' does not name a type.

'Scheduler' does not name a type
If you have an idea I would be very grateful. Thanks in advance.

I suspect nRF52840 Adafruit library uses their own scheduler and that creates name conflict. I have not looked into it unfortunately

Yeah, @arkhipenko is right.
Just change all the names of the "Scheduler" to something else and you are good to go.
Here's a copy of the library with the Scheduler changed to SchedulerAUCO.
